GENERAL DESCRIPTION
The AMSREF-01 is a precision voltage reference, which provides a stable +10V output, which can be adjusted over a ± 3%
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 12V to 40V with a typical current drain of 650µA.
Low cost, low noise and low power makes the AMSREF-01 an excellent choice whenever a stable voltage reference is
required. Applications include D/A and A/D converters, portable instrumentation and digital voltmeters.
Max •• Current sources
P-P
The AMSREF-01 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.
