Part Number : AMS4040
Function : Micropower shunt voltage reference
Manufacturers : Advanced Monolithic Systems Inc
The AMS4040 is a two-terminal micropower band-gap voltage reference diode featuring a very low dynamic impedance and good temperature coefficient, operating over a 250µA to 100mA current range. On-chip trimming is used to provide tight voltage tolerance. Since the AMS4040 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 AMS4040 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 AMS4040 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.
