LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS
General Description
The AZ339 series consists of four independent preci-
sion voltage comparators with an offset voltage speci-
fication as low as 2mV. The input common mode
voltage range of these comparators includes ground,
even when operated from a single power supply volt-
age. Operation from split power supplies is also possi-
ble and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
The AZ339 series is designed to directly interface with
TTL and CMOS.
The AZ339 series can be widely used in such applica-
tions as battery charger, cordless telephone, switching
power supply, DC-DC module and PC motherboard.
The AZ339 series are available in 2 Packages: DIP-14
and SOIC-14.
