Operational Amplifiers are tools that possess all the required properties for nearly ideal direct current amplification and hence applied extensively in signal conditioning, filtering or to perform mathematical operations including addition, subtraction, integration and differentiation. They are high gain electronic voltage amplifier with differential input and typically a single ended output. An Operational Amplifier is typically a three-terminal linear device that comprises of two high impedance inputs. Inverting input marked negatively, non-inverting input marked positively and third terminal represents the operational amplifier output port that can both sink and source either voltage or a current. Op-amps are the backbone of analog circuit design. An operational amplifier is fundamentally a voltage magnifying tools constructed to be used with external feedback components such as capacitors and resistors between its output and input terminals. The characteristics of an op-amp circuit includes 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, due to negative feedback.
