TAS2563: IOVDD, VDD funtion

Part Number: TAS2563


Hi team,

Customer use TAS2563 in there system, and they get one question about the IOVDD, VDD.

What does IOVDD and VDD provide power respectively to TAS2563? My understand is all I/O pins are powered by IOVDD; VDD provide power for the internal digital circuit. If so, the IO should be able to withstand the IOVDD input or output. However, the datasheet shows the max input voltage is VDD+0.3V, see the below pic. So I don’t know if my understanding is right. Could you help give some comments to this?

Thanks and best Regards,

Will
