GS393

General Description
The GS393/393A 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 GS393/393A series are compatible with industry standard 393. GS393A
has more stringent input offset voltage than GS393.
Applications
 Battery Charger
 Cordless Telephone
 Switching Power Supply
 DC-DC Module
 PC Motherboard
 Communication Equipment
