I am planning to use an external DAC + amplifier combo to output mono sound from my microcontoller. The ouput from the amplifier would be connected to a single speaker
DAC : PCM5102 AMPLIFIER : PAM8019
The sound data from my mcu is MONO format and both these chips support 2 channels.The I2S data will be mono.
My question is how do I just use the single channel on them? What do I do with the OUTL pin (on PCM5102) and LIN, LOUT-P and LOUT-P pins(n PAM8019)? Do I simply connect them to ground?
I've never worked with audio before so all this is new to me.
Thanks for the help!
