Voltage Comparator Circuit using OPAMPs

A voltage comparator is a circuit which compares the voltages at its input terminals and switches the output to either high or low depending upon which input was high. making a voltage comparator using transistors and other components is quite difficult and makes no sense because we have OPAMPs. We can use 741, LM311, LM324, […]
