National Semiconductor LP339

The LP339 consists of four independent voltage comparators designed specifically to operate from a single power supply and draw typically 60 µA of power supply drain current over a wide range of power supply voltages. These comparators also feature a common-mode range which includes ground, even when operated from a single supply. The LP339 was specifically designed to interface with the CMOS logic family.

GENERAL DESCRIPTION

Operation from split supplies is also possible and the ultra-low power supply drain current is independent of the power supply voltage.

APPLICATIONS

include limit comparators, simple analog-to-digital converters, pulse, square and time delay generators; VCO’s; multivibrators; high voltage logic gates. 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
