NSC LM710CH Voltage comparator Datasheet

General Description
The LM710 series are high-speed voltage comparators intended for use as an accurate, low-level digital level sensor
or as a replacement for operational amplifiers in comparator
applications where speed is of prime importance. The circuit
has a differential input and a single-ended output, with saturated output levels compatible with practically all types of integrated logic.
The device is built on a single silicon chip which insures low
offset and thermal drift. The use of a minimum number of
stages along with minority-carrier lifetime control (gold doping) makes the circuit much faster than operational amplifi-
ers in saturating comparator applications. In fact, the low
stray and wiring capacitances that can be realized with
monolithic construction make the device difficult to duplicate
with discrete components operating at equivalent power levels.
The LM710 series are useful as pulse height discriminators,
voltage comparators in high-speed A/D converters or go,
no-go detectors in automatic test equipment. They also have
applications in digital systems as an adjustable-threshold
line receiver or an interface between logic types. In addition,
the low cost of the units suggests them for applications replacing relatively simple discrete component circuitry.
