AN2310: Comparator with Independently Programmable Hysteresis Thresholds

To operate in the presence of noise, many comparators require some hysterysis to allow graceful output transitions. Combining programmable comparator user modules and internal digital programmable logic (LUTs), it is possible to build a comparator with independently selectable threshold levels. A method of building such a comparator is explored and a sample project is included.
