GENERAL DESCRIPTION  
The AMS1004-1.2 is a two-terminal micropower band-gap voltage reference diode. It features 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 AMS1004-1.2 is a band-gap reference, uses only transistors and resistors, low noise and good  
long term stability result. Careful design of the AMS1004-1.2 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 AMS1004-1.2 makes these reference  
diodes useful for micropower circuitry. This voltage reference 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, making it attractive  
for use in systems where accuracy was previously obtained at the expense of power consumption and trimming.  
The AMS1004-1.2 is operational over a temperature range of 0°C to 70°C and is available in TO-92, SO-8 and SOT-89  
packages. For extended temperature range contact factory.
