ABSTRACT:
A comparator which for example can be used for a digital potentiometer is shown. Specifically, a dual differential input circuit with a push/pull amplifier at the output stage is disclosed wherein a crossing is detected in an inputted signal as the crossing occurs and wherein the push/pull amplifier pair at the output stage provides very fast detection of a crossing. This is particularly useful in acting as a trigger mechanism for changes in a digital potentiometer for example to elements noise caused as "wiper changes" occur.
