LR339

Low Power Low Offset Voltage

Quad Comparators

The LR339 consists of four independent precision

voltage comparators.These were designed specifically

to operate from a signal power supply over a wide range

of voltage.Operation from split power supplies is also

possible and the low power supply current drain is

independent of the magnitude of the power supply

voltage.The LR339 also have a unique characteristic in

that the input common-mode voltage range includes

ground,even though operated from a single power

supply voltage.

DESCRIPTION:

FEATURE:

Low input biasing current: 25nA(Typ.)

Low input offset current:

5.0nA(Typ.)

Low output saturation voltage: 130mV

Output voltage compatible with TTL,CMOS
