USB Powered Stereo Audio Amplifier for LTSpice training

Description:

This USB-powered audio amplifier is used as a practical example for a step-by-step LTSPICE tutorial.

The tutorial covers everything from drawing the schematic to importing third-party SPICE models, analyzing waveforms.

At the end of the video we will build the amplifier and test the actual physical hardware on the bench.
