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.
