19-0887; Rev 5; 7/04 +5V, +10V Precision Voltage References Features The REF01/REF02 are industry-standard precision voltage references. The stable 10V output of the REF01 can be adjusted over a 3% range with minimal effect on temperature stability, while the 5V output REF02 can be adjusted over a 6% range. The 10V REF01 has a single-supply operation over an input voltage range of 13V to 33V, while the 5V REF02 has a single-supply operation over an input voltage range of 7V to 33V. Both devices offer a low-current drain of 1mA. The REF02 also provides a TEMP pin whose output voltage varies linearly with temperature, making this device suitable for a wide variety of temperature-sensing and control applications. For new designs, refer to the MAX6035 or MAX6143 data sheets.

This feature allows the system designer to trim system errors by setting the reference to a voltage other than 10V, including 10.240V for binary applications (see the Typical Operating Circuit).

The temperature coefficient change is approximately 0.7ppm/C for 100mV of output adjustment. _______________________________________________________________________________________ 3 REF01/REF02 +5V, +10V Precision Voltage References ABSOLUTE MAXIMUM RATINGS-REF02 Input Voltage REF02, A, E, H.....................................................................40V REF02C, D...........................................................................30V Continuous Power Dissipation T099 (J) (derate at 7.1mWC above +80C).................500mW CERDIP (2) (derate at 6.7mW/C above +75C) .........500mW Plastic Dip (P) (derate at 5.6mW/C above +36C) .....500mW Small Outline (S) (derate at 5.0mW/C above +55C) ..300mW Storage Temperature Range .............................-65C to +150C Operating Temperature Range REF02A, REF02 ..............................................-55C to +125C REF02E, REF02H .................................................0C to +70C REF02C (except REF02CESA), REF02D .............0C to +70C REF02CESA ......................................................-40C to +85C Output Short-Circuit Duration (to ground or VIN) .......................................................Indefinite Lead Temperature (soldering, 60s) .................................+300C Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.

Adjustment of the output does not significantly affect the temperature performance of the device. Typically, the temperature coefficient change is 0.7ppm/C for 100mV of output adjustment. Temperature Voltage Output The REF02 provides a temperature-dependent output voltage on the TEMP pin. This voltage is proportional to the absolute temperature, and has a scale factor of approximately 2.1mV/C (Figure 1). 830 TEMP VOLTAGE OUTPUT (mV) REF01/REF02 +5V, +10V Precision Voltage References 780 730 680 630 580 530 480 430 -60 -40 -20 0 20 40 60 80 100 120 140 TEMPERATURE (C) Figure 1.
