It has two inputs one of which is the setpoint or desired reference threshold voltage and may be a fixed value or user adjustable depending on the design figure 1. Photodiode amplifier circuit. It outputs a digital signal showing the results.
The symbol of the operational amplifier and comparator are looked the same.
Comparator circuits are widely used to compare physical measurements provided those physical variables can be translated into voltage signals. A comparator is often used to convert an analog signal to a digital signal. Window comparator circuit. Comparators are faster than the operational amplifier.
