GENERAL DESCRIPTION
The AMSREF-02 is a precision voltage reference, which provides a stable +5V, which can be adjusted over a ± 6% range
with minimal effect on temperature stability. Careful design of this device improved its bandgap and as a result excellent
temperature stability is achieved. The operating supply range is 7V to 40V with a typical current drain of 650mA.
Low cost, low noise and low power makes the AMSREF-02 an excellent choice whenever a stable voltage reference is
required. Applications include D/A and A/D converters, portable instrumentation and digital voltmeters. The versatility of
AMSREF-02 is enhanced by its use as a monolithic temperature transducer.
The AMSREF-02 is operational in the full industrial temperature range of -40°C to 85°C and is available in the 8 lead SOIC
and plastic dip (PDIP) packages.
