AS339/339A
LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS
Features
The AS339/339A consist 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 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 is available in DIP-14, SOIC-14 and TSSOP-14
packages, and the AS339A is available in SOIC-14 package.
