GENERAL DESCRIPTION

The AMS9491 is a two-terminal micropower band-gap voltage reference diode. It feature a very low dynamic impedance and

good temperature coefficient, operating over a 10µA to 20mA current range. On-chip trimming is used to provide tight voltage

tolerance. Since the AMS9491 is a band-gap reference, uses only transistors and resistors, low noise and good long-term

stability result. Careful design of the AMS9491 has made the device exceptionally tolerant of capacitive loading, making it

easy to use in almost any reference application. The wide dynamic operating range allows its use with widely varying supplies

with excellent regulation. The extremely low power drain of the AMS9491 makes this reference diode useful for micropower

circuitry.

The AMS9491 can be used to make portable meters, regulators or general purpose analog circuitry with battery life

approaching shelf life. Further more, the wide operating current allows it to replace older references with a tight tolerance part.

The AMS9491 is operating over a 0°C to 70°C temperature range and is available in TO-92 and SO-8 packages.
