GENERAL DESCRIPTION
The AMS1009 is a precision band-gap voltage reference diode. This voltage reference features a very low dynamic impedance
and good temperature coefficient, operating over a wide current range of 400µA to 10mA. On-chip trimming is used to
provide tight tolerance and minimize temperature drift. A third terminal allows the reference voltage to be adjusted to
±5%
to
calibrate out system errors.
The AMS1009 is used as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry,
and the 2.5V make it easy to obtain a stable reference from 5V logic supplies.
The AMS1009 is available in TO-92 and SO-8 packages operating over a 0°C to 70°C temperature range.
