Hello and hola to the original poster of this question!
Because that topic has been closed unanswered I have recreated it as I have the same exploded IC inside my Sonos S16 Amp. Does anyone have their S16 open at the moment and can tell me or send me pics of this Texas Instruments chip labelled as U16 on the circuit board? From the other post I see LM??002 perhaps….

I would really appreciate these quite modern devices not going into landfill in my country and any help will be appreciated. By me and by the earth of the future!
