FEATURES
GENERAL DESCRIPTION
The AMS124 is a two-terminal micropower band-gap voltage reference diode featuring low dynamic impedance and good
temperature coefficient, operating over a 50µA to 4mA current range. On-chip trimming is used to provide tight voltage
tolerance. Since the AMS124 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 AMS124 is operational in the full industrial temperature range of -40 C to 85 C and is available in small space saving
SOT-23 package.
