Analog comparators are always in the shadow of their more popular cousin, the ubiquitous op amp. Designers can draw on a wealth of application notes for op amps, but not so for comparators. One ...

Fig 1. The traditional window comparator with a single op amp has interactions between the output and the reference voltage that creates uncertainty in its hysteresis window width. Fig 2. Adding a ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

In 1938, the Journal of Scientific Instruments published details of a comparator circuit that converted a slowly varying input signal into an abrupt change in output voltage. Based on cross-coupled ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...
