LP339

Ultra-Low Power Quad Comparator

General Description

The LP339 consists of four independent voltage compara-

tors designed specifically to operate from a single power

supply and draw typically 60 µA of power supply drain cur-

rent over a wide range of power supply voltages. Operation

from split supplies is also possible and the ultra-low power

supply drain current is independent of the power supply volt-

age. These comparators also feature a common-mode

range which includes ground, even when operated from a

single supply.

Applications

include

limit

comparators,

simple

analog-to-digital converters, pulse, square and time delay

generators; VCO’s; multivibrators; high voltage logic gates.

The LP339 was specifically designed to interface with the

CMOS logic family. The ultra-low supply current makes the

LP339 valuable in battery powered applications.

Advantages

n Ultra-low power supply drain suitable for battery

applications

n Single supply operation

n Sensing at ground

n Compatible with CMOS logic family

n Pin-out identical to LM339

Features
