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 ...

While both operational amplifiers and voltage comparators have been with us since before 1970, the similarities and differences tend to be vague. This discussion will help in understanding this ...

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 ...
