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 the ADR02.
