Data Sheet POWER OFFSET VOLTAGE DUAL COMPARATORS General Description
AS393/393A consist independent precision voltage comparators with typical offset voltage 1.0mV high gain. They specifically designed operate from single power supply over wide range voltages. Operation from split power supply also possible power supply current drain independent magnitude power supply voltage. AS393/393A series compatible with industry standard 393. AS393A more stringent input offset voltage than AS393. AS393 available standard DIP-8, SOIC-8 TSSOP-8 packages, AS393A available standard DIP-8 SOIC-8 packages.
