Operational amplifier or Op-Amp is a voltage amplifier, which has differential input and single ended output. Generally external components are attached in the feedback circuit to get the required response from the Op-Amp. It is among the most commonly used circuits in electronics being used in variety of applications.
L165V is a power operational amplifier, which is manufactured using monolithic integrated circuit in Pentawatt package. This package is intended for as power Op-Amp applications. High voltage gain and high output power capability provides superior performance.

Ideal operational amplifier has infinite open loop gain, infinite input impedance and infinite bandwidth of operation. Also it has zero output impedance and zero offset voltage. Since it has infinite input impedance there will be current through the input terminals and there will be no voltage drop at the input.
Op-Amp has two input terminals called inverting input and non-inverting input terminal. Input signal applied to the inverting input will have a phase shift when appearing at the output terminal, and the signal applied at the non-inverting terminal will have no phase shift at the output. Depending upon how the external components are connected to the Op-Amp it can perform as summer, integrator, differentiator, and amplifier.
ApplicationsL165V can be used in following applications
· Inverting amplifier
· Non inverting amplifier
· Motor control circuits
· Differentiator and integrator circuits
