LM614

Quad Operational Amplifier and Adjustable Reference

General Description

The LM614 consists of four op-amps and a programmable

voltage reference in a 16-pin package. The op-amp

out-performs most single-supply op-amps by providing

higher speed and bandwidth along with low supply current.

This device was specifically designed to lower cost and

board space requirements in transducer, test, measurement

and data acquisition systems.

Combining a stable voltage reference with four wide output

swing op-amps makes the LM614 ideal for single supply

transducers, signal conditioning and bridge driving where

large common-mode-signals are common. The voltage ref-

erence consists of a reliable band-gap design that maintains

low dynamic output impedance (1Ωtypical), initial tolerance

(2.0%), and the ability to be programmed from 1.2V to 5.0V

via two external resistors. The voltage reference is very

stable even when driving large capacitive loads, as are

commonly encountered in CMOS data acquisition systems.

As a member of National’s new Super-Block™family, the

LM614 is a space-saving monolithic alternative to a multichip

solution, offering a high level of integration without sacrificing

performance.

Limits

(Note 7)

Units

Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the

device beyond its rated operating conditions.

Note 2: Input voltage above V+is allowed.

Note 3: More accurately, it is excessive current flow, with resulting excess heating, that limits the voltages on all pins. When any pin is pulled a diode drop below

V−, a parasitic NPN transistor turns ON. No latch-up will occur as long as the current through that pin remains below the Maximum Rating. Operation is undefined

and unpredictable when any parasitic diode or transistor is conducting.

Note 4: Junction temperature may be calculated using TJ=T

A+PD

jA. The given thermal resistance is worst-case for packages in sockets in still air. For packages

soldered to copper-clad board with dissipation from one comparator or reference output transistor, nominal θjA is 90˚C/W for the WM package.

Note 5: Human body model, 100 pF discharged through a 1.5 kΩresistor.

Note 6: Typical values in standard typeface are for TJ= 25˚C; values in boldface type apply for the full operating temperature range. These values represent the

most likely parametric norm.

Note 7: All limits are guaranteed at room temperature (standard type face) or at operating temperature extremes (bold type face).

Note 8: Slew rate is measured with op amp in a voltage follower configuration. For rising slew rate, the input voltage is driven from 5V to 25V, and the output voltage

transition is sampled at 10V and @20V. For falling slew rate, the input voltage is driven from 25V to 5V, and the output voltage transition is sampled at 20V and 10V.

Note 9: VRis the Cathode-feedback voltage, nominally 1.244V.

Note 10: Average reference drift is calculated from the measurement of the reference voltage at 25˚C and at the temperature extremes. The drift, in ppm/˚C, is

106•∆VR/(VR[25˚C] •∆TJ), where ∆VRis the lowest value subtracted from the highest, VR[25˚C] is the value at 25˚C, and ∆TJis the temperature range. This parameter

is guaranteed by design and sample testing.

Note 11: Hysteresis is the change in VRcaused by a change in TJ, after the reference has been “dehysterized”. To dehysterize the reference; that is minimize the

hysteresis to the typical value, cycle its junction temperature in the following pattern, spiraling in toward 25˚C: 25˚C, 85˚C, −40˚C, 70˚C, 0˚C, 25˚C.

Note 12: Low contact resistance is required for accurate measurement.

Application Information

VOLTAGE REFERENCE

Reference Biasing

The voltage reference is of a shunt regulator topology that

models as a simple zener diode. With current I

flowing in the

“forward” direction there is the familiar diode transfer func-

tion. I

flowing in the reverse direction forces the reference

voltage to be developed from cathode to anode. The cath-

ode may swing from a diode drop below V

−

to the reference

voltage or to the avalanche voltage of the parallel protection

diode, nominally 7V. A 5.0V reference with V

=3Visal-

lowed.

The reference equivalent circuit reveals how V

is held at the

constant 1.2V by feedback, and how the FEEDBACK pin

passes little current.

To generate the required reverse current, typically a resistor

is connected from a supply voltage higher than the reference

voltage. Varying that voltage, and so varying I

, has small

effect with the equivalent series resistance of less than an

ohm at the higher currents. Alternatively, an active current

source, such as the LM134 series, may generate I

Capacitors in parallel with the reference are allowed. See the

Reference AC Stability Range typical curve for capacitance

values—from 20 µA to 3 mA any capacitor value is stable.

With the reference’s wide stability range with resistive and

capacitive loads, a wide range of RC filter values will perform

noise filtering.

Adjustable Reference

The FEEDBACK pin allows the reference output voltage,

, to vary from 1.24V to 5.0V. The reference attempts to

hold V

at 1.24V. If V

is above 1.24V, the reference will

conduct current from Cathode toAnode; FEEDBACK current

always remains low. If FEEDBACK is connected to Anode,

then V

= 1.24V. For higher voltages FEEDBACK is

held at a constant voltage above Anode—say 3.76V for V

= 5V. Connecting a resistor across the constant V

generates

a current I=V

/R1 flowing from Cathode into FEEDBACK

node.AThevenin equivalent 3.76V is generated from FEED-

BACK toAnode with R2=3.76/I. For a 1% error, use R1 such

that I is greater than one hundred times the FEEDBACK bias

current. For example, keep I ≥5.5µA.

Understanding that V

is fixed and that voltage sources,

resistors, and capacitors may be tied to the FEEDBACK pin,

a range of V

synthesized.

Application Information (Continued)

Hysteresis

The reference voltage depends, slightly, on the thermal his-

tory of the die. Competitive micro-power products

vary—always check the data sheet for any given device. Do

not assume that no specification means no hysteresis.

OPERATIONAL AMPLIFIERS

Any amp or the reference may be biased in any way with no

effect on the other amps or reference, except when a sub-

strate diode conducts (see Guaranteed Electrical Character-

istics (Note 1)). One amp input may be outside the

common-mode range, another amp may be operated as a

comparator, another with all terminals floating with no effect

on the others (tying inverting input to output and

non-inverting input to V

−

on unused amps is preferred).

Choosing operating points that cause oscillation, such as

driving too large a capacitive load, is best avoided.

Op Amp Output Stage

These op amps, like their LM124 series, have flexible and

relatively wide-swing output stages. There are simple rules

to optimize output swing, reduce cross-over distortion, and

optimize capacitive drive capability:

1. Output Swing: Unloaded, the 42µA pull-down will bring

the output within 300 mV of V

−

over the military tempera-

ture range. If more than 42µAis required, a resistor from

output to V

−

will help. Swing across any load may be

improved slightly if the load can be tied to V

, at the cost

of poorer sinking open-loop voltage gain

2. Cross-over Distortion: The LM614 has lower cross-over

distortion (a 1 V

deadband versus 3 V

for the

LM124), and increased slew rate as shown in the char-

acteristic curves.Aresistor pull-up or pull-down will force

class-A operation with only the PNP or NPN output

transistor conducting, eliminating cross-over distortion

3. Capacitive Drive: Limited by the output pole caused by

the output resistance driving capacitive loads, a

pull-down resistor conducting 1 mA or more reduces the

output stage NPN r

until the output resistance is that of

the current limit 25Ω. 200pF may then be driven without

oscillation.

Op Amp Input Stage

The lateral PNP input transistors, unlike most op amps, have

EBO

equal to the absolute maximum supply voltage. Also,

they have no diode clamps to the positive supply nor across

the inputs. These features make the inputs look like high

impedances to input sources producing large differential and

common-mode voltages.
