Hello all,
I have attached the audio stage of my design.
The TDA8541 is fed by a DAC 0-3.3V.
In normal use the sound will go through the 8 Ohms speaker but I want the possibility to plug headphones or speakers. I don't need to be in stereo but I want both ears/speakers to be working if a stereo jack is plugged.
The way it is currently wired works but I wonder if it would be better to connect the sleeve of the jack to ground instead.
The down side of doing such thing is that I would have an external lead connected to the ground and therefore possibly acting like a point of entry for noise... But on the other hand I don't want to damage headphones/speakers.
How would you do it?
Thanks,
Alex
