GENERAL DESCRIPTION
NC = NO CONNECT. DO NOT CONNECT ANYTHING
ON THESE PINS. SOME OF THEM ARE RESERVED
FOR FACTORY TESTING PURPOSES.
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.

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.

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 25°C, and the
temperature coefficient is approximately 1.9± 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.

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 AD8±01, AD820, or OP1177 (all of which would result in
less than a 100 V change in ΔVOUT) See Figure 19. Without
buffering, even tens of microamps drawn from the TEMP pin
can cause VOUT to fall out of specification.

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 µV/V
PSRR of the OP02E will create a 20 ppm change (3 µV/V ×
35 V/5 V) in output current over a 25 V range. For example, a
5 mA current source can be built (R = 1 kΩ) with 350 MΩ
output impedance.
NOTES
1. REF02 SHOULD BE THERMALLY CONNECTED
TO SUBSTANCE BEING HEATED.
2. NUMBERS IN PARENTHESES ARE FOR A
SETPOINT TEMPERATURE OF 60°C.

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).
