OP-AMP with Negative Feedback

Differential Input and Differential Output Amplifier

Differential Input and Differential Output Amplifier: In almost all the applications, the op-amp is employed with a single-ended or unbalanced output. However, there are certain applications in which a differential output is desired. The differential input and differential output amplifier is widely employed as a pre-amplifier and in driving push-pull arrangements. One possible arrangement of …

Op Amp Differential Amplifier Circuit Diagram and its Operation

Op Amp Differential Amplifier Circuit Diagram and its Operation: An ideal difference amplifier amplifies only the difference between two signals; it rejects any common signals to the two input terminals. For instance, a microphone system amplifies an audio signal applied to one terminal of a difference amplifier, and rejects any 50 Hz noise signal or …
