hello i got this ic and i wanna build an mono amp with it to get 20w.
in the data sheet they say that the input is differential left - left + and same for right.
my question is how do i take an mp3 player with an analouge output
and connect the mp3 output into the ic input
is this possible?
else what device playing diffrential outputs?
thanks

A differential input doesn't "know" or care if your source output is balanced or not. A differential input only looks at the difference between the "-" and "+" input. So connect the mp3 player left output to the left "+" input, right output to right "+" input, and both left and right "-" inputs to the mp3 player output ground.
