The Differential Amplifier is the super quality amplifier used in operational amplifiers. As its name implies, it amplifies the difference of two input signals i.e. V1 and V2 and gives the output. Hence it is called as differential amplifier.
Read MoreWhat is Differential Amplifier? Explain in detailsAn operational amplifier (Opamp) is a versatile device which can be used to amplify AC as well as DC signals. It is manufactured in the form of integrated circuit package. It can perform different mathematical operations like addition, subtraction, integration, taking the derivative, comparison, etc. Hence it is known as operational amplifier.

Before discussing about what is transducer, first we shall see basic difference between sensor and a transducer. They both are used to sense a change within the environment they are surrounded by or an object they are attached to. However, a sensor will give an output in the same format and a transducer will convert the measurement into an electrical signal.
