Light Sensor with Hysteresis, by Frank Rivard
The feedback given to the comparator provides some hysteresis and the potentiometer allows to adjust the sensitivity of the detector for darkness. I am quite sure you could inverse R1 and R2...
Comparator Circuits - Electronic Circuits & Hobby Projects
One is to add hysteresis to the comparator, but, if the noise level is high, the hysteresis must be correspondingly high... Frequency Comparator Draws 8 µA : 03/03/97 EDN-Design Ideas
Adding Extra Hysteresis to Comparators - Maxim/Dallas
How to add extra hysteresis to common comparator circuits... Analog comparators are always in the shadow of their more popular cousin, the ubiquitous op amp.
MIC841/2 Comparator with Reference
The MIC842 incorporates a voltage reference and comparator with fixed internal hysteresis; two external resistors are used to set the switching threshold voltage.
Noise insensitive comparator
a comparator whose switching characteristics exhibit hysteresis: a comparator whose switching characteristics do not exhibit hysteresis; means for coupling the first and second input signals to the...
TechOnline Adding Extra Hysteresis to Comparators
One consequence of that scarcity is that customers call the Maxim applications line for help when adding comparator hysteresis. This note explains how to add hysteresis to some common comparator...
Comparator - Wikipedia, the free encyclopedia
A dedicated voltage comparator may also contain additional features such as an accurate, internal voltage reference and adjustable hysteresis. It is incorrect to consider a comparator as a device with...
Frequency window comparator has hysteresis
Frequency window comparator has hysteresis W Dijkstra, Consultant, Waalre, The Netherlands...
Selecting the Right Comparator - Maxim/Dallas
For comparators without hysteresis, the voltage difference between the inputs needed to switch the comparator is the offset voltage, rather than the zero voltage required by an ideal comparator.
