General Description
Features
Data Sheet
AS393/393A
The AS393/393A consist of two independent precision
voltage comparators with a typical offset voltage of
1.0mV and high gain. They are specifically designed to
operate from a single power supply over wide range of
voltages. Operation from split power supply is also
possible and the low power supply current drain is
independent of the magnitude of the power supply
voltage.
The AS393/393A series are compatible with industry
standard 393. AS393A has more stringent input offset
voltage than AS393.
The AS393 is available in standard DIP-8, TDIP-8,
SOIC-8, TSSOP-8 and MSOP-8 packages, AS393A is
available in standard DIP-8 and SOIC-8 packages.
· Wide Supply Voltage Range
- Single Supply: 2.0V to 36V
- Dual Supplies: ±1.0V to ±18V
· Low Supply Current Drain: 0.6mA
· Low Input Bias Current: 25nA (Typical)
· Low Input Offset Current: ±5.0nA (Typical)
· Low Input Offset Voltage: 1.0mV (Typical)
· Input Common Mode Voltage Range Includes
Ground
· Differential Input Voltage Range Equals to the
Power Supply Voltage
· Low Output Saturation Voltage: 200mV at 4mA
· Open Collector Output
Applications
· Battery Charger
· Cordless Telephone
· Switching Power Supply
· DC-DC Module
