A Difference Amplifier or a Differential Amplifier amplifies the difference between the two input signals. This division enables circuit designers to recognize quickly, understand, and choose optimal configurations. The symbol of the op-amp with the associated terminals and ports is shown on Figure 1(a) and (b). When dealing with operational amplifiers there are two very important rules to remember about inverting amplifiers, these are: "No current flows into the input terminal" and that "V1 always equals V2". An op-amp amplifies the difference between one input and the other, while neither individual input is itself amplified. An operational amplifier, or op-amp for short is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.In this configuration, an op-amp produces an output potential that is typically hundreds of thousands of times larger than the potential difference between its input terminals, and is a voltage amplifying device designed .
