Improvements to the 4*118W / 8Ohm chip from TI with I2S input.
Possible that this has been out there for some time, however I noticed just now the TAS6684 on the TI pages, initial specs seem to be the same, but certain aspects are improved like the ability to handle up to 13A current where the TAS6584/82 designs has a maximum limit of 10A so a 30% improvement.
The publicly available information is very limited as it is not yet in production with extremely limited availability.
Nice to know that it is pin compatible with the TAS6584:
The one thing that is completely new with the TAS6684 seems to be: "Real-time temperature monitor for each channel"
Other than that there is a difference in the maximum output switching frequency, which is 2.1MHz for the "old" TAS6584, and slightly lower 2MHz for the new TAS6684.
