GENERAL DESCRIPTION
The REF01 precision voltage reference provides a stable 10 V
output that can be adjusted over a 3% range with minimal effect
on temperature stability. Single-supply operation over an input
voltage range of 12 V to 40 V, a 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
REF01 an excellent choice whenever a stable voltage reference is
required. Applications include DACs and ADCs, portable
instrumentation, and digital voltmeters. Full military
temperature range devices with screening to MIL-STD-883 are
available. For new designs, refer to ADR01.

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.

Figure 12. Output Adjustment
The REF01 trim terminal can be used to adjust the output
voltage over a 10 V ± 300 mV range. This feature lets the
system designer trim system errors by setting the reference
to a voltage other than 10 V. The output also can be set exactly
to 10.000 V or to 10.240 V for binary applications.
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.

PRECISION CURRENT SOURCE
A current source with 25 V output compliance and excellent
output impedance can be obtained using this circuit. REF01
keeps the line voltage and power dissipation constant in the
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 creates an 8 ppm
change (3 µV/V × 25 V/10 V) in output current over a 25 V
range. For example, a 10 mA current source can be built
(R = 1 kΩ) with 300 MΩ output impedance.

SUPPLY BYPASSING
For best results, it is recommended that the power supply pin be
bypassed with a 0.1 µF disc ceramic capacitor.
REFERENCE STACK WITH EXCELLENT LINE
REGULATION
Three REF01s can be stacked to yield 10 V, 20 V, and 30 V
outputs. An additional advantage is near-perfect line regulation
of the 10.0 V and 20.0 V output. A 32 V to 60 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 20 V regulator.
In general, any number of REF01s can be stacked this way.
For example, 10 devices will yield outputs of 10 V, 20 V,
30 V . . . 100 V. The line voltage can change from 105 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).
