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.

FEATURES
• ±5 mV (±0.2%) Max. Initial Tolerance (A grade)
