OPAMP Basics Operational amplifiers are convenient building blocks that can be used to build amplifiers, filters, and even an analog computer. Op Amp is short form of operational amplifier. An op amp is an electronic unit that behaves like a voltage controlled voltage source. An ideal op amp has zero current into its two input terminals and the voltage difference between the two input terminals is equal to zero.

Stolp, rev, An operational amplifier is basically a complete highgain voltage amplifier in a small package. Opamps were originally developed to perform mathematical operations in An Operational Amplifier, or opamp for short, is fundamentally a voltage amplifying device designed to be used with external feedback components such as resistors and capacitors between its output and input terminals. These feedback components determine the resulting function or operation of the amplifier and by virtue of the different.

The basic op amp hookup of Figure 12 below applies a signal to the () input, and a (generalized) network delivers a fraction of the output voltage to the () input terminal. This constitutes feedback, with the op amp operating in closedloop fashion. digital, the op amp had become so useful in so many circuits that deal with real (analogue) quantities such as sound, light, heat and motion, that the op amp is now a widely varied and indispensable part of electronics equipment.
