    Hi,

    For TAS5805M,

    1. The I2C address setting for two devices should be different,

    2. Each PVDD bank (pin27,28; pin 15,16) should have a 0.1uF+10uF cap placed as close as possible.

    For TPA3156,

    1. Fault pin should not pulled up to 24V. It's not a high voltage pin.

    Thanks!

    Regards,

    Sam
