GENERAL DESCRIPTION

The AMS285-2.5/AMS385-2.5 are two-terminal micropower band-gap voltage reference diodes. They feature a very low

dynamic impedance and good temperature coefficient, operating over a 20µA to 20mA current range. On-chip trimming is

used to provide tight voltage tolerance. Since the AMS285-2.5/AMS385-2.5 is a band-gap reference, uses only transistors and

resistors, low noise and good long term stability result. Careful design of the AMS285-2.5/AMS385-2.5 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

AMS285-2.5/AMS385-2.5 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 AMS285-2.5 is operational in the full industrial temperature range of -40°C to 85°C while AMS385-2.5 is operating

over a 0°C to 70°C temperature range. The AMS285-2.5/AMS385-2.5 are available in TO-92, SO-8 and SOT-89 packages.
