Hi Sir,

 

     We are going to evaluate ADAU1452 in EVB , but we find some noise when we adjust the EQ and Volume at single tone ex: 1k / 500khz input.

     I try to make project as below. I will find the some noise when i adjust the volume or EQ.

     Could you help to check the issue in advance?
