3 Description

The LPV3xx-N are low power (9-µA per channel at

5 V) versions of the LMV3xx op amps. This is another

addition to the LMV family of commodity op amps.

The LPV3xx-N are the most cost effective solutions

for the applications where low voltage, low power

operation, space saving and low price are needed.

The LPV3xx-N have rail-to-rail output swing capability

and the input common-mode voltage range includes

ground. They all exhibit excellent speed-power ratio,

achieving 152 kHz of bandwidth with a supply current

of only 9 µA.

The LPV321-N is available in space saving 5-Pin

SC70, which is approximately half the size of 5-Pin

SOT-23. The small package saves space on PC

boards, and enables the design of small portable

electronic devices. It also allows the designer to place

the device closer to the signal source to reduce noise

pickup and increase signal integrity.

The chips are built with Texas Instruments's

advanced submicron silicon-gate BiCMOS process.

The LPV3xx-N have bipolar input and output stages

for improved noise performance and higher output

current drive.

7 Detailed Description

7.1 Overview

The LPV321-N, LPV358-N, and LPV324-N devices are micropower (10-µA) versions of the popular LMV3xx-N.

The LPV321-N is the single-channel version. The LPV358-N is the dual, and the LPV324-N is the quad. The

LPV32x-N are the most cost effective solution for applications where low power and low voltage operation, space

efficiency, and low-price are important. The LPV3x-N have rail-to-rail output swing capability and the input

common-mode voltage range includes ground. They all exhibit excellent speed to power ratio, achieving 152 kHz

of bandwidth and 0.1-V/µs slew rate with 10 mA of supply current.

7.2 Functional Block Diagram

7.3 Feature Description

7.3.1 Size

The small footprints of the LPV3xx-N packages save space on printed circuit boards, and enable the design of

smaller electronic products (such as cellular phones, pagers, or other portable systems). The low profile of the

LPV3xx-N make them possible to use in PCMCIA type III cards.

7.3.2 Signal Integrity

Signals can pick up noise between the signal source and the amplifier. By using a physically smaller amplifier

package, the LPV3xx-N can be placed closer to the signal source, reducing noise pickup and increasing signal

integrity.

7.3.3 Simplified Board Layout

These products help avoid using long printed-circuit traces in the PCB. This means no additional components,

such as capacitors and resistors, are needed to filter out unwanted signals due to the interference between the

long printed-circuit traces.

7.3.4 Low Supply Current

These devices help maximize battery life. They are ideal for battery powered systems.

7.3.5 Low Supply Voltage

TI provides ensured performance at 2.7 V and 5 V. These specifications ensure operation throughout the battery

lifetime.

7.3.6 Rail-to-Rail Output

Rail-to-rail output swing provides maximum possible dynamic range at the output. This is particularly important

when operating on low-supply voltages.

Feature Description (continued)

7.3.7 Input Includes Ground

Allows direct sensing near GND in single supply operation.

The differential input voltage may be larger than V+without damaging the device. Protection should be provided

to prevent the input voltages from going negative more than −0.3 V (at 25°C). An input clamp diode with a

resistor to the IC input terminal can be used.

7.4 Device Functional Modes

The LPV3xx-N can be operated as a single-supply or a dual-supply operational amplifier depending on the

application.

7.4.1 Capacitive Load Tolerance

The LPV3xx-N can directly drive 200 pF in unity-gain without oscillation. The unity-gain follower is the most

sensitive configuration to capacitive loading. Direct capacitive loading reduces the phase margin of amplifiers.

The combination of the amplifier's output impedance and the capacitive load induces phase lag. This results in

either an underdamped pulse response or oscillation. To drive a heavier capacitive load, circuit in Figure 37 can

be used.

Figure 37. Indirectly Driving A Capacitive Load Using Resistive Isolation

In Figure 37, the isolation resistor (RISO) and the load capacitor (CL) form a pole to increase stability by adding

more phase margin to the overall system. The desired performance depends on the value of RISO. The bigger the

RISO resistor value, the more stable VOUT is. Figure 38 is an output waveform of Figure 37 using 100 kΩfor RISO

and 1000 pF for CL.

Device Functional Modes (continued)

The circuit in Figure 39 is an improvement to the one in Figure 37 because it provides DC accuracy as well as

AC stability. If there were a load resistor in Figure 37, the output would be voltage divided by RISO and the load

resistor. Instead, in Figure 39, RFprovides the DC accuracy by using feed-forward techniques to connect VIN to

RL. Caution is needed in choosing the value of RFdue to the input bias current of the LPV3xx-N. CFand RISO

serve to counteract the loss of phase margin by feeding the high frequency component of the output signal back

to the amplifier's inverting input, thereby preserving phase margin in the overall feedback loop. Increased

capacitive drive is possible by increasing the value of CF. This in turn slows down the pulse response.

7.4.2 Input Bias Current Cancellation

The LPV3xx-N family has a bipolar input stage. The typical input bias current of LPV3xx-N is 1.5 nA with 5-V

supply. Thus a 100-kΩinput resistor causes 0.15 mV of error voltage. By balancing the resistor values at both

inverting and noninverting inputs, the error caused by the amplifier's input bias current is reduced. The circuit in

Figure 40 shows how to cancel the error caused by input bias current.

8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The LPV3xx-N family of amplifiers is specified for operation from 2.7 V to 5 V (±1.35 V to ±2.5 V). Many of the

specifications apply from –40°C to 125°C. They provide ground-sensing inputs as well as rail-to-rail output swing.

Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in

the Typical Characteristics.

8.2 Typical Applications

8.2.1 Simple Low-Pass Active Filter

A simple low-pass filter is shown in Figure 41.

Figure 41. Simple Low-Pass Active Filter Schematic

8.2.1.1 Design Requirements

The low-pass filter is shown in Figure 41 passes low frequencies and attenuate frequencies above corner

frequency (fc) at a roll-off rate of 20 dB/Decade.

8.2.1.2 Detailed Design Procedure

The low-frequency gain (ω→o) is defined by −R3/R1. This allows low-frequency gains other than unity to be

obtained. The filter has a −20 dB/decade roll-off after its corner frequency fc. R2must be chosen equal to the

parallel combination of R1and R3to minimize errors due to bais current. The frequency response of the filter is

shown in Figure 42.

Typical Applications (continued)

Note that the single op amp active filters are used in to the applications that require low quality factor, Q (≤10),

low frequency (≤5 kHz), and low gain (≤10), or a small value for the product of gain times Q (≤100). The op

amp must have an open loop voltage gain at the highest frequency of interest at least 50 times larger than the

gain of the filter at this frequency. In addition, the selected op amp must have a slew rate that meets the

requirements in Equation 2.

Slew Rate ≥0.5 × (ωHVOPP) × 10−6V/µsec

where

•ωHis the highest frequency of interest

• VOPP is the output peak-to-peak voltage (2)

8.2.2 Difference Amplifier

The difference amplifier allows the subtraction of two voltages or, as a special case, the cancellation of a signal

common to two inputs. It is useful as a computational amplifier in making a differential to single-ended conversion

or in rejecting a common mode signal.

Figure 43. Difference Amplifier Schematic

8.2.3 Instrumentation Circuits

The input impedance of the previous difference amplifier is set by the resistor R1, R2, R3, and R4. To eliminate

the problems of low input impedance, one way is to use a voltage follower ahead of each input as shown in the

following two instrumentation amplifiers.

Typical Applications (continued)

8.2.3.1 Three Operating Amplifier Instrumentation

The quad LPV324 can be used to build a three-op-amp instrumentation amplifier as shown in Figure 44

Figure 44. Three-op-amp Instrumentation Amplifier Schematic

The first stage of this instrumentation amplifier is a differential-input, differential-output amplifier, with two voltage

followers. These two voltage followers assure that the input impedance is over 100 MΩ. The gain of this

instrumentation amplifier is set by the ratio of R2/R1. R3should equal R1and R4equal R2. Matching of R3to R1

and R4to R2affects the CMRR. For good CMRR over temperature, low drift resistors should be used. Making R4

Slightly smaller than R 2and adding a trim pot equal to twice the difference between R 2and R4will allow the

CMRR to be adjusted for optimum.

8.2.3.2 Two Operating Amplifier Instrumentation

A two-op-amp instrumentation amplifier can also be used to make a high-input-impedance DC differential

amplifier (Figure 45). As in the three-op-amp circuit, this instrumentation amplifier requires precise resistor

matching for good CMRR. R4should equal to R1and R3must equal R2.

Figure 45. Two-op-amp Instrumentation Amplifier Schematic

(4)

8.2.3.3 Single-Supply Inverting Amplifier

There may be cases where the input signal going into the amplifier is negative. Because the amplifier is

operating in single supply voltage, a voltage divider using R3and R4is implemented to bias the amplifier so the

input signal is within the input common-common voltage range of the amplifier. The capacitor C1is placed

between the inverting input and resistor R1to block the DC signal going into the AC signal source, VIN. The

values of R1and C1affect the cutoff frequency in Equation 5.

fc = 1/2πR1C1(5)

Typical Applications (continued)

As a result, the output signal is centered around mid-supply (if the voltage divider provides V+/2 at the non-

inverting input). The output can swing to both rails, maximizing the signal-to-noise ratio in a low voltage system.

9 Power Supply Recommendations

The LPV3xx-N is specified for operation from 2.7 V to 5.5 V; many specifications apply from –40°C to 125°C.

Parameters that can exhibit significant variance with regard to operating voltage or temperature are presented in

the Typical Characteristics.

Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high

impedance power supplies. For more detailed information on bypass capacitor placement, see Layout Guidelines

section.

10 Layout

10.1 Layout Guidelines

For best operational performance, use good PCB layout practices including:

• Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the operational

amplifier. Bypass capacitors are used to reduce the coupled noise by providing low impedance power

sources local to the analog circuitry.

• Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as close

to the device as possible. A single bypass capacitor from V+ to ground is applicable for single supply

applications.

• Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective

methods of noise suppression. One or more layers on multilayer PCBs are usually devoted to ground planes.

A ground plane helps distribute heat and reduces EMI noise pickup. Make sure to physically separate digital

and analog grounds, paying attention to the flow of the ground current. For more detailed information, see

Circuit Board Layout Techniques (SLOA089).

• To reduce parasitic coupling, run the input traces as far away from the supply or output traces as possible. If

it is not possible to keep them separate, it is much better to cross the sensitive trace perpendicular as

opposed to in parallel with the noisy trace.

• Place the external components as close to the device as possible. Keeping RF and RG close to the inverting

input minimizes parasitic capacitance, as shown in Figure 47.

• Keep the length of input traces as short as possible. Always remember that the input traces are the most

sensitive part of the circuit.

• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly reduce

leakage currents from nearby traces that are at different potentials.

IMPORTANT NOTICE

Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its

semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers

should obtain the latest relevant information before placing orders and should verify that such information is current and complete.

TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated

circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and

services.

Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is

accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced

documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements

different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the

associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.

Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers

remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have

full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products

used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with

respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous

consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and

take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will

thoroughly test such applications and the functionality of such TI products as used in such applications.

TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,

including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to

assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any

way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource

solely for this purpose and subject to the terms of this Notice.

TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI

products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,

enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically

described in the published documentation for a particular TI Resource.

Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that

include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE

TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY

RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or

other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information

regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or

endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the

third party, or a license from TI under the patents or other intellectual property of TI.

TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR

REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO

ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF

MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL

PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,

INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF

PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,

DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN

CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN

ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949

and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.

Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such

products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards

and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must

ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in

life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.

Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life

support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all

medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.

TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).

Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications

and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory

requirements in connection with such selection.

Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-

compliance with the terms and provisions of this Notice.
