    Hi, CK,

    I have reviewed the schematic and have a couple comments.

    • If MICBIAS is not directly connected to VDD, the decoupling cap should not be populated, please refer to this wiki to find more information about this.
    • We recommend to connect the unused inputs of the device to a cap connected to ground.

    Other than these, the schematic seems fine.

    Best Regards,
