The comparator is a high-gain amplifier that is used to amplify a small differential signal at its input, and drive the output to one of two output states. Figure 1 shows the basic comparator circuit, ...

Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...

Comparators are great at turning little signals into large digital outputs. In the example described here, a friend wanted to detect the presence of a small 60-Hz ac signal centered on 2.5 V dc. When ...
