Dear Sir/Madame,
On my customer schematic, I don't use the inputs signals IN1L/Aux1, IN1R/Aux2, IN3L, IN3R, IN4L and IN4R.
No problem if all pins are left floating? I'm not sure if they can be totally disabled by software. Or do you recommend connecting a pull-down to them to avoid possible interference?
For the output pins, I don't use speaker outputs (RECP, RECM, SPKP and SPKM), do you recommend connecting them to resistor of equal value to the corresponding speaker resistor (8Ω and 32Ω respectively)?
In case LOL and LOR or HPL and HPR are not going to be used, what do you recommend me to connect them? Floating left or pull-down?
Best Regards,
Jorge Brenes.
