In previous articles—Common op-amp circuits, Op amps do integration, and The practical op-amp differentiator is quite versatile—we looked at some classic op amp circuits. These circuits used negative ...

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 ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...

The industry standard LM2901 quad and LM2903 dual comparators and LM2902 quad and LM2904 dual op amps, from Diodes Inc., feature an extended operating temperature range of -40 ºC to +125 ºC. The parts ...

While both operational amplifiers and voltage comparators have been with us since before 1970, the similarities and differences tend to be vague. This discussion will help in understanding this ...

Engineers often encounter difficulty when attempting to accurately rectify low-amplitude AC signals using standard diode-based circuits. The primary issue arises from the diode’s forward voltage drop, ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...
