As we can see in our day-to-day, technology has advanced exponentially, making possible things unimaginable just a few years ago. As a form of unnecessary effort, devices with remote commands are the most common nowadays, whether by computational means, by voice command, among others. With that in mind, this article will demonstrate the use and application of amplifiers with addendum for remote adjustments, where it will be placed on all circuit characteristics, components, among others. Before the final exclusions about the project itself, we pass a little about the history and major applications of operational amplifiers, more specifically the class D amplifiers, which are the most indicated in the application of audio systems. We will also cover some other classes of amplifiers, as well as their working principles, architecture and applications. We will also bring the results, practical and theoretical, demonstrating good agreement with the objectives sought in the design phase and also similar ones in the literature. The execution of the project will bring a very broad view of the application of the amplifier gain command through remote access, opening up new opportunities for applications and uses in various aspects, in addition to bringing curiosity and encouragement as research in the world of microelectronics.
