Fig 1. The traditional window comparator with a single op amp has interactions between the output and the reference voltage that creates uncertainty in its hysteresis window width. Fig 2. Adding a ...

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 ...

My last column (“Designing with comparators,” EDN, March 29, 2001, pg 56) discussed basic comparator theory, and this column adds hysteresis to comparators to eliminate multiple switching on the ...

HONG KONG: National Semiconductor Corp. has introduced a new low-power precision comparator with integrated 2.048V reference that provides adjustable hysteresis for the highest-accuracy signal ...

Intended for monitoring low-voltage levels in battery-operated systems, the MIC841 and MIC842 ultra-low-power comparators feature on-chip precision voltage references with 1.25% accuracy. These Micrel ...
