An operational amplifier (op-amp) is an electronic component that is easily configured to perform a variety of useful functions. We will discuss models of op-amps that will allow us to design and analyze op-amp circuits for testing and analysis.An operational amplifier (op-amp) can perorm the following duties…
· Isolating parts of circuits (i.e., buffering),
· Amplifying voltages,
· Performing mathematical operations (addition and subtraction).
