TPA2012D2: About the replacement of INL and INR

user6323968

Part Number: TPA2012D2

Due to the layout arrangement of the board, the output of the speaker amplifier needs to be connected in the opposite direction.

Is it no problem to connect the right channel of the DAC to INL and the left channel of the DAC to INR for TPA2012D2?

Hi,

Can you post a simple diagram to show your proposed connections? It should not matter if you connect opposite channels, just consider the stereo image would be reversed.

Please see the attached file.
The DAC Left output inputs Speaker Left side, the DAC Right output inputs Speaker Right side.

Only TPA2012D2 is reversed.
We believe that this will have no effect on the sound.
