A high gain DC amplifier that has a high input impedance and a low output impedance. Op-amps are the most basic type of linear integrated circuits.

An amplifier designed to perform computing or transfer operations and that has the following characteristics: (1) very high gain, (2) very high input impedance, and (3) very low output impedance. OpAmp Manufacturers

It is a high-gain, high-input impedance amplifier which performs mathematical operations when suitably wired, like integrated circuit.

a highly stable, gain, DC amplifier, usually produced as a single integrated circuit

a device which is a high gain amplifier whose gain and response characteristics are determined by external components

a high gain, differential, voltage amplifier

a large set of transistors and a capacitor, in an integrated circuit casing

an extremely high gain differential voltage amplifier--a device that compares the voltages of two inputs and produces an output voltage that's many times the difference between their voltages

a very high gain amplifier

Op-Amps are general-purpose integrated circuits that act as basic building blocks for implementation of linear functions. The op amp gain and response characteristics are determined by external components, representing the front end on an electronic system, capturing weak signals and amplifying them for further processing. It is important to note that when amplifying the signal the wave shape does not change.

An amplifying circuit used in most audio devices.

(op-amp) One of the basic building blocks of analogue circuits - a high gain stable amplifier with a voltage gain of 100 to 100,000 or more.

(op amp) (circuit) Originally, an amplifier to perform mathematical operations. An amplifier with two differentially connected inputs, with high voltage gain, and with one output - which ideally is at zero volts when both inputs are at zero volts. It must also be capable of accepting negative feedback without oscillating.

A high-gain amplifier with a large amount of negative feedback and high input impedance.

A special type of amplifier and exhibiting very high open-loop gain, very high input impedance, very low output impedance, and good rejection of common-mode signals.

An operational amplifier, usually referred to as an 'op-amp' for brevity, is a DC-coupled high-gain electronic voltage amplifier with differential inputs and, usually, a single output. In its ordinary usage, the output of the op-amp is controlled by negative feedback which, because of the amplifier's high gain, almost completely determines the output voltage for any given input.
