PCM2903C: Review of Design

Part Number: PCM2903C

Hi Team,

We are using PCM2903CDBR & PCM6260QRTVRQ1 in our design.

Below is the block diagram of our design.

Can you please help us to review the schematics?

Regards,

Antony.

    Hi Antony,

    Everything looks good here to me.

    Only things I want to confirm:

    1) Are you using single ended mic sources? I noticed the negative input is grounded.

    2) If you don't intend on using the HID pins, I would ground them instead of leaving them floating.

    Best regards,
