An operational amplifier (often op-amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.[1] In this configuration, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals. Operational amplifiers had their origins in analog computers, where they were used to perform mathematical operations in many linear, non-linear and frequency-dependent circuits. The popularity of the op-amp as a building block in analog circuits is due to its versatility. Due to negative feedback, the characteristics of an op-amp circuit, its gain, input and output impedance, bandwidth etc. are determined by external components and have little dependence on temperature coefficients or manufacturing variations in the op-amp itself.

Introduction
In this chapter we will discuss the basic operation of the op amp, one of the most
common linear design building blocks.
In section 1 the basic operation of the op amp will be discussed. We will concentrate on
the op amp from the black box point of view. There are a good many texts that describe
the internal workings of an op amp, so in this work a more macro view will be taken.
There are a couple of times, however, that we will talk about the insides of the op amp. It
is unavoidable.
In section 2 the basic specifications will be discussed. Some techniques to compensate for
some of the op amps limitations will also be given.
Section 3 will discuss how to read a data sheet. The various sections of the data sheet and
how to interpret what is written will be discussed.
Section 4 will discuss how to select an op amp for a given application.

Amplifier design using OpAmp
Resistance value of resistor used in amplifiers are preferred in the range of (1K,1M)ohm (this may change depending on the IC technology). Small resistance might induce too large current and large resistance consumes too much chip area
OpAmp non-idealities
Output voltage swing: real OpAmp has a maximum and minimum limit on the output voltages
OpAmp transfer characteristic is nonlinear, which causes clipping at output voltage if input signal goes out of linear range
The range of output voltages before clipping occurs depends on the type of OpAmp, the load resistance and power supply voltage.
Output current limit: real OpAmp has a maximum limit on the output current to the load
The output would become clipped if a small-valued load resistance drew a current outside the limit
Slew Rate (SR) limit: real OpAmp has a maximum rate of change of the output voltage magnitude
limit
SR can cause the output of real OpAmp very different from an ideal one if input signal frequency is too high
Full Power bandwidth: the range of frequencies for which the OpAmp can produce an undistorted sinusoidal output with peak amplitude equal to the maximum allowed voltage output
