    Hello Asaishi-san,

    We never designed the TPA3138D2 with the intent of it being configured in a single-ended output so there's a bit of an unknown. We never tested it under those conditions. The customer is welcome to try but we can't guarantee the device will operate within expected datasheet behavior. 

    We do have a few devices that were designed to be able to operate with a single-ended output configuration. I would recommend looking at the TPA3244. It's got a higher output power but this device was validated to run in single-ended output configuration!

    Best Regards,
