TPA2008D2: PCB Layout checking

Dylan You
Intellectual 2630 points
Part Number: TPA2008D2

Dear Teams,

Have a nice day and nice to meet you! Here is Dylan from China NWC MM team FAE. I am coming to approach you because I found there is a potential business growth opportunities for Class-D audio amplifier. I found you are also the owner of the TPA2008D2. Could I ask some support need from your team? If you are not the right person for technical support need, could you loop the correct person?

 

Support Need:

  1. Customer is confusing whether they should placed the PCB layout of TPA2008D2 with codec analog together for all, or the AMP input terminal should be placed into analog side? Or they should placed this chipset and speaker into digital side? Do you have any suggestions?
  2. In another case, due the position of speaker, there is no way to place AMP TPA2008D2 and speaker to the analog part of the Codec. Could you also give some suggestions?

Thanks!

Dylan

    Hello Dylan, 

    Just wanted to summarize the email conversation here. 

    It is best to use analog GND for the TPA2008D2 and the analog GND should be shorted to the digital GND somewhere on your schematic. As for the speakers, since they are a differential connection and don't need to connect to GND, there should be no problem with their placement. 

    I am closing this thread for now, but let us know if you have any further questions. 

    Best Regards
