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 D/A and A/D converters,
portable instrumentation, and digital voltmeters. Full military
temperature range devices with screening to MIL-STD-883
are available. For new designs, please refer to ADR01.
