Part Number: TPA3136D2

To implement volume control on the TPA3136D2, do i have to place a logarithmic pot on the plimit pin or on the left and right inputs?

Hello Diego

The Plimit circuit isn't a high accuracy circuit so we would recommend modifying the input. Also in the Plimit circuit we have on the EVM we use a linear trimmer pot not a logarithmic pot.

Best regards,

Luis
