GENERAL DESCRIPTION

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

instrumentation, and digital voltmeters. Full military

temperature range devices with screening to MIL-STD-883 are

available. For new designs, refer to ADR01.
