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 ...

So, you have selected an MCU with an analog-to-digital converter (ADC) and analog comparator peripherals for your cost-sensitive application. You then realize that your sensor signal needs to be ...

You think of op amps as amplifiers because, no kidding, it is right in the name. But just like some people say, “you could do that with a 555,” [Doctor Volt] might say, “you can do that with an op amp ...

(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 ...
