Product Brief
LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS
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.
The AS393/393A series are compatible with industry stan-
dard 393. AS393A has more stringent input offset voltage
than AS393.
