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 instru-
mentation, and digital voltmeters. Full military temperature
range devices with screening to MIL-STD-883 are available.
For new designs, refer to ADR01.

OUTPUT
The REF01 trim terminal can be used to adjust the output voltage
over a 10 V
±
300 mV range. This feature allows the system designer
to trim system errors by setting the reference to a voltage other than
10 V. Of course, the output can also be set to exactly 10.000 V or
to 10.240 V for binary applications.
Adjustment of the output does not significantly affect the tempera-
ture performance of the device. The temperature coefficient change
is approximately 0.7 ppm/°C for 100 mV of output adjustment.

device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

Burn-in is available on commercial and industrial temperature range parts in CERDIP, PDIP, and TO-can packages.
2
For devices processed in total compliance to MIL-STD-883, add 883 after part number. Consult factory for 883 data sheet.
3
For availability and burn-in information on SOIC package, contact your local sales office.
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 the
REF01 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.
