Description

The AS331 consists of a single precision voltage comparator with a typical input offset voltage of 1.0mV and high voltage gain. It is 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 AS331 is available in standard SOT-23-5 package.

Feature(s)

Wide Supply Voltage Range:
Single Supply: 2V to 36V
Dual Supplies: ±1V to ±18V
Low Supply Current at VCC=5V: 0.4mA
Low Input Bias Current: 25nA (Typical)
Low Input Offset Current:5nA (Typical)
Low Input Offset Voltage: 1mV (Typical)
Input Common Mode Voltage Range Includes Ground
Differential Input Voltage Range Equals to the Power Supply Voltage
Low Output Saturation Voltage at 4mA: 200mV (Typical)
Open Collector Output

Application(s)

Battery Charger
Cordless Telephone
Switching Power Supply
DC-DC Module
PC Motherboard
Communication Equipment
