I posted on diyaudio website ,audiophile version of TPA3116D2 https://www.diyaudio.com/forums/class-d/337182-sublimed-tpa3116d2.html showing on YouTube it's superiority compared to 300b SE amplifier . When I wanted to explain the functioning of the IC , I found myself rather speculating than explaining . I will ask you to do it instead briefly. when I look the left inputs on figure7.2 page 13 they receive feedback of opposite phase okay , but when you look the right inputs RINP receives OUTPR FB a positive feedback and RINN receives a mysterious OUTPNR FB . Is this a double printing error or political preferences ? the error signal passes two inverting integrators , is the first a low pass function to transform the PWM into analog or the two integrators inverse the ac phase ?
