8.1.1 External Hysteresis

Comparator inputs have no noise immunity within the range of specified offset voltage (±12 mV). For noisy input signals, the comparator output may display multiple switching as input signals move through the switching threshold. The typical comparator threshold of the TLV301x-EP is ±0.5 mV. To prevent multiple switching within the comparason threshold of the comparator, external hysteresis may be added by connecting a small amount of feedback to the positive input. Figure 8-2 shows a typical topology used to introduce hysteresis, described by this equation:

VHYST sets the value of the transition voltage required to switch the comparator output by increasing the threshold region, thereby reducing sensitivity to noise.
