LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS
General Description
Features
AZ393
The AZ393 series consists of two independent preci-
sion voltage comparators with an offset voltage speci-
fication as low as 1mV. 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 AZ393 series is designed to directly interface with
TTL and CMOS.
The AZ393 series can be widely used in such applica-
tions as battery charger, cordless telephone, switching
power supply, DC-DC module and PC motherboard.
