描述 Description

The AS393/393A consist of two independent precision voltage comparators with a typical offset voltage of 1.0mV and high gain. They are 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.

\t?

\tThe AS393/393A series are compatible with industry standard 393. AS393A has more stringent input offset voltage than AS393.
