The answer to the latch advantage is written right into the first sentences of the article!!!
Quote from EDN article "Add hysteresis to a voltage comparator": Positive feedback is a typical technique for distributing hysteresis around a comparator, provided that you have a resistive path between the comparator's output and the noninverting input. Positive feedback forms two threshold voltages that have (or assume) fixed values. In addition, they depend on the saturation values of the comparator's output stage. Plus, the load conditions affect their accuracy. Michael Karas |
