PCM9211 Internal connection of GNDs.

yoshiki hasebe

Dear Sirs,

My customer asked me about internal connection of GNDs (AGND, DGND, GNDRX).

Are there each of GNDs connected internally?

Or are they separated?

Please let me know about above question.

Best Regards,

Hi Y.Hasebe,

The grounds are not connected internally, and we strongly recommend that the grounds be connected externally on the PCB.
