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 ...

Testing a set of analog comparators for hysteresis can be a time-consuming process. You have to accurately find the threshold voltages for numerous devices across variations in fabrication process, ...

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 ...

Linear Technology Corporation announces the LTC6752 family of comparators with fast rise and fall times of 1.2ns and a toggle frequency of 280MHz, making them the fastest CMOS output comparators ...
