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 ...
The comparator is a high-gain amplifier that is used to amplify a small differential signal at its input, and drive the output to one of two output states. Figure 1 shows the basic comparator circuit, ...
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 ...
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 ...
