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 ...
This application note outlines the implementation of a single-supply, triangular wave oscillator using the MAX9000 and some passive components. The application circuit uses an op amp, comparator, and ...
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, ...
