Operation Amplifier 741 Based Projects

Operation Amplifier 741 Based Projects: The op-amp IC 741 is a DC-coupled, high gain differential amplifier with external negative feedback. IC 741 is characterized by the almost infinite open-loop gain (100,000), almost infinite input impedance (2MΩ), and almost zero output impedance (75Ω).

IC 741 is the most popular, cheap, and easy-to-use op-amp. Some popular IC 741 names MCI741, LM741, SN72741, CA741, GS741, etc.

IC741 can be used as an electronic integrator or differentiator, depending on the R-C network in the input and feedback circuit.

Application of Operational amplifier:-

The following lists of circuits functions are designed using op-amp:

Voltage follower, current to voltage converter, summing amplifier, integrator, differentiator, active filter, capacitance multiplier, simulated inductor, voltage to current converter, precision rectifier, analog to digital converter, sample and hold circuit, voltage comparator, servo amplifier.
