Ultra-Low Power Quad Comparator
General DescriptionThe LP339 consistsof four independent voltage compara-
tors designed specificallyto operate froma single power
supply and draw typically60μAof power supply drain cur-
rent overa wide rangeof power supply voltages. Operation
from split suppliesis also possible and the ultra-low power
supply drain currentis independentofthe power supply volt-
age. These comparators also featurea common-mode
range which includes ground, even when operated froma
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 designedto interface with the
CMOS logic family. The ultra-low supply current makes the
LP339 valuablein battery powered applications.
Advantages Ultra-low power supply drain suitablefor battery
applications Single supply operation Sensingat ground Compatible with CMOS logic family Pin-out identicalto LM339
