There are two basic ways to configure the voltage feedback op amp as an amplifier. These are shown in Figure and Figure Figure shows what is known as the inverting configuration. The schematic representation of an op-amp is shown to the left. There are two input pins (non-inverting and inverting), an output pin, and two power pins. The ideal op- amp has infinite gain. It amplifies the voltage difference between the two inputs and that voltage appears at the output. The term operational amplifier, abbreviated op amp, was coined in the s to refer to a special kind of amplifier that, by proper selection of external components, can be configured to perform a variety of mathematical operations. Early op amps were made from vacuum tubes consuming lots .

The op amp will continue to be a vital component of analog design because it is such a fundamental component. Each generation of electronics equipment integrates more functions on silicon and takes more of the analog circuitry inside the IC. An op-amp or operational amplifier is a linear device and extensively used in filtering, signal conditioning, or mainly used for performing mathematical operations such as addition, subtraction, differentiation, and integration. Basically, an op-amp uses external feedback components among the input as well as output terminals of op-amp like resistors and capacitors. The schematic representation of an op-amp is shown to the left. There are two input pins (non-inverting and inverting), an output pin, and two power pins. The ideal op- amp has infinite gain. It amplifies the voltage difference between the two inputs and that voltage appears at the output. The term operational amplifier, abbreviated op amp, was coined in the s to refer to a special kind of amplifier that, by proper selection of external components, can be configured to perform a variety of mathematical operations. Early op amps were made from vacuum tubes consuming lots . Op-amp Parameter and Idealised Characteristic. Open Loop Gain, (Avo) Infinite – The main function of an operational amplifier is to amplify the input signal and the more open loop gain it has the better. Open-loop gain is the gain of the op-amp without positive or negative feedback and for such an amplifier the gain will be infinite but typical real values range from about 20, to , There are two basic ways to configure the voltage feedback op amp as an amplifier. These are shown in Figure and Figure Figure shows what is known as the inverting configuration.
