adau1401 for Echo Cancelling

Hi,

I need to design an echo cancelling circuit for a speakerphone system. I would appreciate if someone can tell me if the ADAU1401 is appropriate for such application. Is the sigma DSP inside this CODEC powerful enough for echo cancelling.

Best regards

Patricio

    Hello Patricio,

    The 1401/1701 will have limited ability for echo cancellation so it will depend on your application. The ADAU1452 or ADAU1466 family will give you enough power for echo cancellation. But, I am not the expert in echo cancellation. So can you give me more details about your application. What is the nature of the echo you need to cancel? How many sound sources (speakers), do the mic, speakers, etc, movable where the echo will change dynamically?

    Then I will ask to get the best answer for you.
