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.
