LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS

General Description

Features

AS339/339A

The AS339/339A consist of four independent preci-

sion 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

wide range of voltages. Operation from split power

supply is also possible and the low power supply cur-

rent drain is independent of the magnitude of the

power supply voltage.

The AS339/339A series are compatible with industry

standard 339. AS339A has more stringent input offset

voltage than AS339.

The AS339 is available in DIP-14, SOIC-14 and

TSSOP-14 packages, AS339A is available in SOIC-14

package.
