General Description
The AS331 consists of a single precision voltage com-
parator with a typical input offset voltage of 1.0mV
and high voltage gain. It is specifically designed to
operate from a single power supply over wide range of
voltages. Operation from split power supply is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
The AS331 is available in standard SOT-23-5 package.
