GENERAL DESCRIPTIONThe 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 D/A and A/D converters,
portable instrumentation, and digital voltmeters. Full military
temperature range devices with screening to MIL-STD-883
are available. For new designs, please refer to ADR01.

REF01Figure 1.Output Adjustment
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 tem-
perature performance of the device. The temperature coefficient
change is approximately 0.7 ppm/°C for 100 mV of output
adjustment.

WAFER TEST LIMITSOutput Adjustment
*Electrical tests are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal yield loss, yield after packaging is not guaranteedfor standard product dice. Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing.

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V 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.
