10.1.1 External Hysteresis

Comparator inputs have no noise immunity within the range of the specified offset voltage. 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 TLV3012-Q1 device is ±0.5 mV. To prevent multiple switching within the comparator threshold of the TLV3012-Q1 device, external hysteresis may be added by connecting a small amount of feedback to the positive input. Figure 10-2 shows a typical topology used to introduce hysteresis, described by Equation 1.

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