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.
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.

OUTPUT ADJUSTMENT
+15V
The REF-01 trim terminal can be used to adjust the 10V output
voltage
±
300mV. This feature allows the system designer to trim
system errors by setting the reference to a voltage other than 10V.
The system can also be set exactly 10.000V, or to 10.240V 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.
