LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS
General Description
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 DIP-14
and SOIC-14 packages
