A few months ago, I wrote a Signal Chain Basics article titled “3 considerations when selecting an op amp.” While that article is very useful for selecting operational amplifiers (op amps) for new ...

The operational amplifier, or op amp, is one of the most basic building blocks used in analog circuits. Ever since single-chip op amps were introduced in the 1960s, thousands of different types have ...

Op amps are generally pretty easy to apply, but there are some practical nonideal behaviors you have to keep in mind. [EEforEveryone] takes a test board with some 2X amplifiers on it and — after some ...

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 ...

This article is part of the TechXchange: Exploring Op Amps. Given the literally thousands of op amps already in vendor standard-product catalogs, it’s easy to think there’s really no need for any more ...

The input offset voltage (V OS) of an operational amplifier (op amp) is modeled as a DC error source that acts like a voltage source on the noninverting input. It can ...
