Dual power supply circuit is the backbone of many electronic systems. Various circuits, especially those involving operational amplifiers, analog devices, and certain digital systems, require both positive and negative voltages to operate properly. This is where Dual Power Supply Circuits come into play. They provide symmetrical voltages (like +12V and -12V, +15V and -15V, etc.) […]
Building a powerful yet compact audio amplifier can greatly enhance your audio experience. This article details how to construct a 3-channel TDA2030 amplifier circuit with separate left, right, and bass channels, powered by a dual ±12V supply. Additionally, it integrates a bass filter circuit, Bluetooth support via a 7805 regulator, and multiple protection features to […]
