Data Sheet
AZ339
The AZ339 series consists of four independent preci- · Wide supply
sion voltage comparators with an offset voltage speci-
- Voltage range: 2.0V to 18V
fication as low as 2mV. The input common mode
- Single or dual supplies: ±1.0V to ± 9V
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-
·
Very low supply current drain: 0.8mA
- independent of supply voltage
ble and the low power supply current drain is · Low input bias current: 25nA
independent of the magnitude of the power supply · Low input offset current: ±5nA
voltage.
· Low input offset: ±2mV
· Input common mode voltage range includes
The AZ339 series is designed to directly interface with
ground
TTL and CMOS.
· Differential input voltage range equals to the
power supply voltage
The AZ339 series can be widely used in such applica- · Low output saturation voltage: 250mV at 4mA
tions as battery charger, cordless telephone, switching · Open-collector output
power supply, DC-DC module and PC motherboard.
Applications
· Battery Charger
· Cordless Telephone
· Switching Power Supply
· DC-DC Module
· PC Motherboard
· Communication Equipment
