An operational amplifier (often op amp or opamp) is a DC-coupled electronic voltage amplifier with a differential input, a (usually) single-ended output, [1] and an extremely high gain. Its name comes from its original use of performing mathematical operations in analog computers .

An example application is the 741 operational amplifier, [4] and Widlar used the circuit as a part in many designs. [5] This circuit is named after its inventor, Bob Widlar, and was patented in 1967. [6] [7]
Basic opamp diode log amplifier. The basic opamp diode log amplifier shown in the diagram utilizes the diode's exponential current-voltage relationship for the opamp's negative feedback path, with the diode's anode virtually grounded and its cathode connected to the opamp's output , used as the circuit output.
Later he devised another new device, the super-beta transistor. It was created in silicon by Talbert and integrated in the LM108 precision operational amplifier, which was released in 1969. [57] These high-gain, very-low-voltage devices were capable of operating at very low input currents within the full military range of operating conditions.
The operational transconductance amplifier (OTA) is an amplifier that outputs a current proportional to its input voltage. Thus, it is a voltage controlled current source (VCCS). Three types of OTAs are single-input single-output, differential-input single-output, and differential-input differential-output (a.k.a. fully differential), [ 1 ...
