I am trying to make a design that makes use of the TDA7265 to amplify sound. I have already had several iterations where I redesigned and ordered a PCB to test out the design, but each seemed to have its own issues. I once got the TDA7265 to work, but only when the sound input wasn't tied to ground, but to some pin on the TDA7265 following some schematic I found somewhere. The problem with that design was that I wanted to have two possible sound sources, sound from an Arduino Due on the same PCB as the sound amplifier (sharing same power source) AND sound from an audio jack input. I have in mind for the audio jack to provide sound like music for most of the time and for the Arduino Due to sometimes produce status messages like "warning, low power."
For this, I made the design seen in the attached schematic, but there is NO sound regardless of the sound source. I have also verified that the Arduino Due produces sound on DAC0 pin. At most you hear some clicking sounds from time to time. The MUTE pin is measured to be 4V. VIN+ is 12V and I have also made sure that the "PLAY" pin is HIGH.
I based my schematic on page 7 of https://pdf1.alldatasheet.com/datasheet-pdf/view/25084/STMICROELECTRONICS/TDA7265.html so I assume it should at least work when no audio jack is connected (as that would just mean a single sound source.) It won't work unfortunately.
Any idea that can point me in the right direction? I don't have much to any experience with sound amplifiers.
