They feature a very low dynamic impedance and good temperature coefficient, operating over a 20µA to 20m A 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. ORDERING INFORMATION: TOL. ±20m V ±38m V ±75m V ±20m V ±38m V ±75m V TO-92 AMS285-2.5AN AMS285-2.5BN AMS285-2.5CN...
