AZ339 Datasheet | AAC

Description The AZ339 series consists of four independent precision voltage parators with an offset voltage specification as low as 2m V. The input mon mode voltage range of these parators 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. The AZ339 series is designed to directly interface with TTL and CMOS. The AZ339 series can be widely used in such applications as battery charger, cordless telephone, switching power supply, DC-DC module and PC motherboard. Features - Wide supply - Voltage range: 2.0V to 18V - Single or dual supplies: ±1.0V to ± 9V Very low supply current drain: 0.8m A - independent of supply voltage Low input bias current: 25n A Low input offset current: ±5n A Low input offset: ±2m V Input mon mode voltage range includes ground Differential input voltage range equals to the power supply voltage Low output saturation voltage: 250m V at 4m A Open-collector output - - - - - - - - Applications - - - - - - Battery Charger Cordless Telephone Switching Power Supply DC-DC Module PC Motherboard munication Equipment DIP-14 SOIC-14 Figure 1.
