My caller last week was in a real bind. The design was almost done and he had run out of room. He needed help. The system needed a comparator function and the circuit board was full. After going over ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

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 ...

(Editor's Note: There are links to the previous parts of this series at the end, below the author's biography.) Determining if one voltage is greater than or less than another voltage is the job for a ...
