LP365N DIP-16

Micropower Programmable Quad Comparator

General Description
The LP365 consists of four independent voltage comparators.
The comparators can be programmed, four at the
same time, for various supply currents, input currents, response
times and output current drives. This is accomplished
by connecting a single resistor between the VCC
and ISET pins.
These comparators can be operated from split power supplies
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 transistor
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 A/D converters,
VCO, multivibrators, voltage converters, power sequencers,
and high performance V/F converters, and RTD
linearization.
