GENERAL DESCRIPTION

FEATURES

This device consists of four independent precision voltage

comparators with an offset voltage specification as low as 2mV

max for CM339.

All these comparators were designed

specifically to operate from a single power supply over a wide

range of voltages. Operation from split power supplies is also

possible. These Comparators also have a unique

characteristic in that the input common mode voltage range

includes ground even though operated from a single power

supply voltage.

!

Wide single supply voltage range or dual supplies for all

devices: +2V to +36V or

± 1V to ± 18V

!

Very low supply current（1.1mA）independent of supply

voltage（1.4mW/comparator +5V）

!

Low input bias current: 25nA typ

!

Low input offset current:

±5nA typ

!

Low input offset voltage:

±1mV typ

!

Input common-mode voltage range includes ground

!

Low output saturation voltage : 250mV typ,（Io = 4mA）

!

Differential input voltage range equal to the supply

voltage

!

TTL, DTL, ECL, MOS, CMOS compatible output
