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 650
A.
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.

OUTPUT ADJUSTMENT
The REF-02 trim terminal can be used to adjust the 5 Volt output
voltage
300mV. This feature allows the system designer to trim
system errors by setting the reference to a voltage other than 5V.
The system can also be set exactly 5.000V, or to 5.12V for binary
applications.
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature
coefficient change is approximately 0.7ppm/
C for 100mV of
output adjustment.
