Infographics : A Brief about IC 741 Op Amp

In the year 1963, the first op-amp was invented by “Fairchild Semiconductors”. The term operational amplifier is the full form of an op-amp and it is one kind of IC (integrated circuits). An op-amp is a DC-coupled high gain voltage amplifier with a differential i/p and a single o/p. In this structure, an operational amplifier generates an o/p potential that is usually many times larger than the potential difference between its i/p terminals.

Op-Amps had their roots in analog computers, where they were used to accomplish mathematical operations in several, linear, non-linear & frequency-dependent circuits. The popularity of this IC as a basic building block in analog circuits is due to its flexibility. Due to its characteristics, features these are determined by an exterior component and also have a slight dependence on temperature coefficients otherwise manufacturing differences in the IC itself.

Nowadays, operational amplifiers are the most commonly used integrated circuits. The applications of these ICs include an immense array of industrial, scientific, and consumer devices. The cost of the several typical op-amps is low in reasonable production volume; but some hybrid, integrated op-amps with different performance conditions may cost over 100 dollars. Operational amplifiers may be packed as apparatuses, or used as fundamentals of more compound integrated circuits.

The operational amplifier is one kind of differential amplifier. Various kinds of differential amplifiers include the instrumentation amplifier, the isolation amplifier, the negative feedback amplifier, and the fully differential amplifier. The IC 741 looks like a ‘small chip’. But, it is a general-purpose. You need to know basic information about this. This infographic shows the pins of the IC 741 operational amplifier, its operation, pin configuration, applications. Notice the triangular shape in the IC denotes an Op-Amp integrated circuit.
