LOW POWER LOW OFFSET VOLTAGE SINGLE COMPARATOR

AS331

General Description

Features

The AS331 consists of a single precision voltage com-

parator 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.

Wide Supply Voltage Range

- Single Supply: 2V to 36V

- Dual Supplies: ±1V to ±18V

Low Supply Current at V =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

The AS331 is available in standard SOT-23-5 package.

Differential Input Voltage Range Equals to the

Power Supply Voltage

Low Output Saturation Voltage at 4mA: 200mV

(Typical)

Open Collector Output
