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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.

Note 3: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C.
Note 4: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX
and TMIN, divided by TMAX - TMIN. The measured temperatures are 0°C, 25°C and 70°C.
