unfinshed KiCAD design of an audio amplifier board with TDA7498
information about the amp can be found here: https://www.st.com/en/audio-ics/tda7498.html
I did not finish the schematic and there is no board layout. Missing are mainly the 3.3V supply and the frequency shift circuit. I stopped working on it and changed to using another chip for my usecase due to lacking documentation from ST micro.
