Hi Team,

If customer wants to check if TPA2015D1 can do mixer from a regular Codec (ALC888S), single-ended L/R output.

Can we connect codec single-ended R to TPA2015 IN+ and codec L to TPA2015 IN-?

My TINA simulation looks ok, but want to verify again, thanks!

Hi Andrew,

I would rather suggest something like the implementation below from another TPA amplifier:

The connection you're using may work, but if input signals are the same they may be eliminated due to differential subtraction.

Thanks for feedback, TPA2011D1 should work for this case.
