Hello So,

The TAS5719 does support PBTL but only in post LC filter. I believe that this e2e post from my colleague will be helpful for you: https://e2e.ti.com/support/audio/f/6/t/395484?tisearch=e2e-sitesearch&keymatch=tas5719%2520pbtl

All the best,

Carolina

Hello Carolina,

I had read this post already but I am not clear the connection after LPF.

For speaker output1, chip outputA short with outputC.

For speaker output2, chip outputB short with outputD.

Is this right? It connection is applied on the EVM but not work.

Is the connection wrong or miss something?

Best regards
