Hello,
I found this app note mostly helpful (App Note). To get the Speaker Playback power consumption i was going to take the Headphone+Speaker numbers and then subtract the Headphone number but then realized all cases of speaker output mention "Stereo". However TLV320AIC3100 mentions it is a Mono Class-D Amplifier, not stereo. In the Headphone section 2.2 it mentions for the mono DAC there is ~6.8mW power saving but it mentions nothing like this for the speaker output (unless I missed it).
Does Stereo vs Mono output on the Class-D change the power consumption at all?
Thanks,
Kevin
