Comparators are used in central processing units (CPUs) and microcontrollers (MCUs). Examples of digital comparator include the CMOS 4063 and 4585 and the TTL 7485 and 74682. Note: An XNOR gate is a basic comparator, because its output is "1" only if its two input bits are equal.

What are comparators used for?

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side; VDD in the illustration) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.

What is a comparator used for in engineering?

Comparators are generally used for linear measurements. And it gives only dimensional differences in relation to a basic dimension of the object. ... A comparator can be it mechanical, Pneumatic, or electrical, by the means of amplification of signals, a linearity of the scale within the measuring range should be assured.
