GENERAL DESCRIPTION
The AMS4041 is a two-terminal micropower band-gap voltage reference diode featuring a very low dynamic impedance and
good temperature coefficient, operating over a 60 µA to 100mA current range. On-chip trimming is used to provide tight
voltage tolerance. Since the AMS4041 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. The
extremely low power drain of the AMS4041 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.
The AMS4041 is operational in the full industrial temperature range of -40 °C to 85 °and is available in small space saving
TO-92, SO-8, SOT-89 and SOT-23 packages.
