Application note
Introduction to comparators, their parameters and basic
applications
By Radim Smat
Introduction
After operational amplifiers (op amps), comparators are the most generally used analog,
simple integrated circuits.
Operational amplifiers are well described in many publications and a lot of information can
be found regarding the design and proper use of these devices. On the other hand,
information concerning comparators is much harder to find as they are often considered as
simple devices. This note explains the main parameters of comparators and their limitations
from an application point of view.
