ComparatorsComparators are a type of linear integrated circuit (IC) that is used to compare two input voltages and output a digital signal indicating which of the two inputs is larger. Comparators are commonly used in applications where it is necessary to quickly and accurately compare two analog signals. They can be used, for example, in level detection circuits, in which the comparator outputs a digital signal when the input voltage exceeds a certain threshold. Comparators are typically designed to operate over a wide range of input voltages, and can operate at high speeds, making them suitable for a variety of applications.
