Comparators have an op-amp front end and a digital back end that operates like a gate. The comparator output stage may be an open collector transistor, so it often connects to the logic supply through ...

Although humble in concept, today’s voltage comparators perform a simple basic task: comparing two voltages to determine which is larger. To accomplish this task, they accept two analog signals and ...

Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

The rugged window comparator for higher-power industrial and related applications provides reinforced galvanic isolation, while offering fast response to faults. Comparators are one of the basic ...
