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 ADR02.
