Operational Amplifiers

An operational amplifier, often called an op-amp, is a DC-coupled high-gain electronic voltage amplifier with differential inputs and usually, a single output. Typically the output of the op-amp is controlled either by negative feedback, which largely determines the magnitude of its output voltage gain, or by positive feedback, which facilitates regenerative gain and oscillation.

Operational amplifiers were originally developed to be used in synthesizing mathematical operations in analog computers, hence their name. Because of recent advances in semiconductor technology, they have become available as integrated circuits. They are widely used when a closely controlled amount of gain or some form of signal processing is necessary in an electronic system.

Through our website, engineers can easily track and order operational amplifiers from different suppliers, distributors, representatives and manufacturers according to your specified parameters.

Manufacturers leveraged with the facility to build up strategic relation and network with a chain of distributors and suppliers of operational amplifiers; the same is the benefit leveraged to the suppliers and distributors too.
