Operational amplifier An operational amplifier (often op amp or opamp) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output. In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals. Handbook of Operational Amplifier Applications (Rev. B) from Burr Brown – I uncovered a couple of treasures, this handbook on op amp applications and one on active RC networks. These old publications, from 1963 and 1966, respectively, are some of the finest works on op amp theory that I have ever seen. Nevertheless, they contain some material that is hopelessly outdated.
