DESCRIPTION

The AO331 is Rail-to-Rail input CMOS comparator featuring Low-power and Open-Drain output.

The AO331 consists of a single precision voltage comparator with a typical input offset voltage of 1.0mV and high voltage gain.

The AO331 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 AO331 is available in SOT-25 package.
