GENERAL DESCRIPTION
The AMS04 and the AMS05 are two-terminal, band-gap voltage reference diodes, with an output voltage of 1.25V for the
AMS04 and 2.5V for the AMS05. These devices feature low dynamic impedance and good temperature coefficient, operating
over a wide current range. Since the band-gap reference of these devices 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 AMS04 and AMS05 can be used for portable meters, regulators, data acquisition converters and
telecommunication.
The AMS04 and AMS05 are operational over a temperature range of 0°C to 70°C and are available in TO-92 and SO-8
packages.
