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.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The
guaranteed specifications apply only for the test conditions listed.

Note 3: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and
TMIN, divided by TMAX - TMIN. The measured temperatures are 0°C, 25°C and 70°C.
