LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS

AS339/339A

General Description

Features

The AS339/339A consist of four independent preci-

sion voltage comparators with a typical offset voltage

of 2.0mV 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 cur-

rent drain is independent of the magnitude of the

power supply voltage.

Wide Supply Voltage Range

- Single Supply: 2.0V to 36V

- Dual Supplies: ±1.0V to ±18V

Low Supply Current Drain: 0.9mA

Low Input Bias Current: 25nA (Typical)

Low Input Offset Current: ±5.0nA (Typical)

Low Input Offset Voltage: 2.0mV (Typical)

Input Common Mode Voltage Range Includes

Ground

The AS339/339A series are compatible with industry

standard 339. AS339A has more stringent input offset

voltage than AS339.

Differential Input Voltage Range Equals to the

Power Supply Voltage

Low Output Saturation Voltage: 200mV at 4mA

Open Collector Output

The AS339 is available in DIP-14, SOIC-14 and

TSSOP-14 packages, AS339A is available in DIP-14

and SOIC-14 packages
