GENERAL DESCRIPTION  
The AMS285-1.2/AMS385-1.2 are two-terminal micropower band-gap voltage reference diodes. They 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 AMS285-1.2/AMS385-1.2 is a band-gap reference, uses only transistors and  
resistors, low noise and good long-term stability result. Careful design of the AMS285-1.2/AMS385-1.2 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  
AMS285-1.2/AMS385-1.2 makes these reference diodes useful for micropower circuitry. These voltage references 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 AMS285-1.2 is operational in the full industrial temperature range of -40°C to 85°C while AMS385-1.2 is operating  
over a 0°C to 70°C temperature range. The AMS285-1.2/AMS385-1.2 are available in TO-92, SO-8 and SOT-89 packages.
