GENERAL DESCRIPTION
The REF02 precision voltage reference provides a stable 5 V output that can be adjusted over a 6% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 7 V to 40 V, low current drain of 1 mA, and excellent temperature stability are achieved with an improved band gap design. Low cost, low noise, and low power make the REF02 an excellent choice whenever a stable voltage reference is required. Applications include DACs and ADCs, portable instrumentation, and digital voltmeters. The versatility of the REF02 is enhanced by its use as a monolithic temperature transducer. For new designs, refer to ADR02.

Absolute maximum ratings apply to both DICE packaged parts, unless otherwise noted. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions outside of those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliability.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

REF02 OUTPUT ADJUSTMENT
The REF02 trim terminal can be used to adjust the output voltage over a 5 V 300 mV range. This feature lets the system designer trim system errors by setting the reference to a voltage other than 5 V. The output also can be set to exactly 5.000 V or to 5.12 V for binary applications.

TEMPERATURE MONITORING
As described previously, the REF02 provides a TEMP output (Pin 3) that varies linearly with temperature. This output can be used to monitor the temperature change in the system. The voltage at VTEMP is approximately 550 mV at 25C, and the temperature coefficient is approximately 1.96 mV/C (see Figure 18).
Figure 14. Output Adjustment Circuit
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature coefficient change is approximately 0.7 ppm/C for 100 mV of
output adjustment.

3 TEMP TRIM GND 4 0.1F
A voltage change of 39.2 mV at the TEMP pin corresponds to a 20C change in temperature. The TEMP function is provided as a convenience rather than a precise feature. Since the voltage at the TEMP node is acquired from the band gap core, current pulling from this pin will have a significant effect on VOUT. Care must be taken to buffer the TEMP output with a suitable low bias current op amp, such as the AD8601, AD820, or OP1177 (all of which would result in less than a 100 V change in VOUT) See Figure 19. Without buffering, even tens of microamps drawn from the TEMP pin can cause VOUT to fall out of specification.

PRECISION CURRENT SOURCE
A current source with 35 V output compliance and excellent output impedance can be obtained using this circuit. REF02 keeps the line voltage and power dissipation constant in device; the only important error consideration at room temperature is the negative supply rejection of the op amp. The typical 3 V/V PSRR of the OP02E will create a 20 ppm change (3 V/V x 35 V/5 V) in output current over a 25 V range. For example, a 5 mA current source can be built (R = 1 k) with 350 M output impedance.

Figure 20. Temperature Controller
REFERENCE STACK WITH EXCELLENT LINE REGULATION
Two REF01s and one REF02 can be stacked to yield 5.000 V, 15.000 V, and 25.000 V outputs. An additional advantage is near-perfect line regulation of the 5.0 V and 15.0 V output. A 27 V to 55 V input change produces an output change that is less than the noise voltage of the devices. A load bypass resistor (RB) provides a path for the supply current (ISY) of the 15.000 V regulator. In general, any number of REF01s and REF02s can be stacked this way. For example, 10 devices will yield 10 outputs in 5 V or 10 V steps. The line voltage can change from 100 V to 130 V. However, care must be taken to ensure that the total load currents do not exceed the maximum usable current (typically 21 mA).
