Hi team
MPN;TPA3123dD2
Detailed description: when Ti demo board is used for debugging, there are several problems:
1.24v power supply and 4 Ω load. When the output power reaches more than 20W, the output will have the same sound source as the input source (the connected cement resistance is not a speaker), and those below 20W are normal;
2. The same frequency sound as the input source will appear when no-load, and it will be found that the smaller the gain is, the smaller the sound will be; The question now is, do you know where the sound comes from?
Best Regards,
William
