LP265LP365 Micropower Programmable

Quad Comparator

General Description

The LP365 consists of four independent voltage compara-

tors The comparators can be programmed four at the

same time for various supply currents input currents re-

sponse times and output current drives This is accom-

These comparators can be operated from split power sup-

plies or from a single power supply over a wide range of

voltages The input can sense signals at ground level even

with single supply operation The unique output NPN tran-

sistor stages are uncommitted to either power supply They

can be connected directly to various logic system supplies

so that they are highly flexible to interface with various logic

families

Application areas include battery power circuits threshold

detectors zero crossing detectors simple serial AD con-

verters VCO multivibrators voltage converters power se-

quencers and high performance VF converters and RTD

linearization
