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 REF02 use as a monolithic temperature transducer. For new designs, refer to ADR02.
