Description

The AS339/339A consists of four independent precision voltage comparators with a typical offset voltage of 2.0mV and high gain. They are specifically designed to operate from a single power supply over a 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 AS339/339A series are compatible with industry standard 339. The AS339A has more stringent input offset voltage than the AS339.

The AS339/339A is available in SO-14 package.
