LM710

Voltage Comparator

General Description

The LM710 series are high-speed voltage comparators in-

tended 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 satu-

rated output levels compatible with practically all types of in-

tegrated 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 dop-

ing) 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 lev-

els.

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 re-

placing relatively simple discrete component circuitry.
