Abstract— A car audio power amplifier is presented that uses a frequency compensation scheme which avoids large compensation capacitors around the MOS power transistors, while retaining the bandwidth and stable load range of nested miller compensation. THD is 0.005%@(1kHz, 10W), SNR is 108dB, and the amplifier is stable for any passive load up to

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 TDA2050.

You only need a few capacitors to make a decent stereo amplifier out of it. It is so simple to build that I put it together on a stripboard in just a few hours. 2.5W * 2 Stereo Amplifier. The amplifier circuit diagram shows a 2.5W * 2 stereo amplifier. You can also make a 5W mono amplifier out of it.
