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
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.
