In this list you will find Op-Amp Circuits Projects. The op-amp IC 741 is a DC-coupled, high gain differential amplifier with external negative feedback. IC 741 is characterized by almost infinite open loop gain (100,000), almost infinite input impedance (2MΩ) and almost zero output impedance (75Ω). Other Op-Amp circuits includes audio amplifier LM358, comparator IC LM324 and other dual channel IC.
Here we have presented a list of various mini electronics projects circuits that are used to solve 100 of daily life problems. The simple 741 op-amp circuit design ideas presented here are not only interesting but also very amusing to build. The included circuit ideas using IC 741 like inverting and non-inverting amplifiers, tone control and regulated power supply, Automatic Staircase Lamp ON Project, Automatic Corridor Light turn ON Project based on Op-amp will surely intrigue you. Circuit diagrams are also attached with the description and benefit of each projects.
