8.2 Typical Applications

Comparators are used to differentiate between two different signal levels. For example, a comparator differentiates between an over-temperature and normal-temperature condition. However, noise or signal variation at the comparison threshold causes multiple transitions. This application example sets upper and lower hysteresis thresholds to eliminate the multiple transitions caused by noise.
