LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS AZ393/393C

Data Sheet
General Description
The AZ393/393C series consists of two independent
precision voltage comparators with an offset voltage
specification 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 AZ393/393C series is designed to directly inter-
face with TTL and CMOS. AZ393C has more
stringent input offset voltage than AZ393.
The AZ393/393C series can be widely used in applica-
tions such as battery charger, cordless telephone,
switching power supply, DC-DC module and PC
motherboard.
The AZ393/393C series are available in standard pack-
ages of DIP-8 and SOIC-8.
