A common first-circuit for op-amp learners is to build an audio amplifier. If that is the goal, the OPM-01 needs a slight modification for the output stage. That mod, also known as OPM-02, increases the transistor count to 7- …

The LM3886 is by far the best sounding amplifier, but it’s a fairly involved project. If you’re just starting to build audio amplifiers, I’d recommend working your way up to it by starting with the TDA2003, then moving up to the …

Assembled Small Power Amplifier Using Op-Amp and Transistors Sometimes we need small power amplifier circuit while we have unused op-amp section in one of our applied chip. Instead of adding more IC (such as LM386 or similar devices), adding two small transistor and several passive components can be cheaper solution if we can employ the unused op-amp section.

In sound electronics, the operational amplifier increases the voltage of the signal, but unable to provide the current, which is required to drive a load. In this tutorial, we will build a 10W amplifier with an 8 Ohms impedance speaker connected to it. We will use an Operational Amplifier and two additional power transistors to deliver the 10 ...

Build a good Audio Buffer Amplifier By Kevin K. Custer W3KKC. General Description: This circuit will amplify voice audio in the range of 50 to 10,000 Hz with little distortion, and have the ability to drive a low impedance load to 16 ohms. The circuit will run from 5 to 18 vdc and give about 20 dB of gain. Concept:
