Comparator: Jump To Navigation Jump To Search

A comparator is an electronic device that compares two voltages or currents and outputs a digital signal to indicate which input is larger. It consists of a high-gain differential amplifier with two analog input terminals and one binary digital output. Comparators are commonly used in devices that measure and digitize analog signals, such as analog-to-digital converters, as well as in relaxation oscillators.
