Traditional digital comparator ICs are electronic analogs of mechanical lever scales. Like their mechanical counterparts, they compare two logical signals and produce an output (typically a voltage ...

Precision instruments often contain specialized components that are essential to their function, but nearly impossible to replace if they fail. [Andre] had just such a problem with an optical ...

Comparators are one of the basic building blocks of analog and mixed-signal designs, providing one small but critical function, as their name indicates. Their role is often to be a “simple” safety ...

Q. Why buy an expensive comparator when an op amp is just as good? A. Because it isn't. My advice to anyone tempted to use an operational amplifier (op amp) as a comparator is the same as Mr. Punch's ...
