General Description
The AZ339 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2mV. The input common mode voltage range of these comparators includes ground, even when operated from a single power supply voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage.

FEATUREs
· Wide Supply Voltage Range
- Single Supply: 2.0V to 18V
- Dual Supplies: ±1.0V to ± 9V
