LOW POWER LOW OFFSET VOLTAGE DUAL COMPARATORS
AZ393/393C
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.
