GENERAL DESCRIPTION
The AMS255 is a two-terminal band-gap voltage reference diode featuring low dynamic impedance and good temperature coefficient, operating over a 100µA to 5mA current range. On-chip trimming is used to provide tight voltage tolerance. Since the AMS255 band-gap reference uses only transistors and resistors, low noise and good long term stability result. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation. These voltage references can be used to make portable meters, regulators or general purpose analog circuitry.
The AMS255 is operational in the full industrial temperature range of -40°C to +85°C and is available in small space saving SOT-23 package.
