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.
