In case of the product would be operated with exceeded guaranteed operating ranges, these protection
features may not operate and some output short circuits may result in the IC being damaged.
Therefore, it should be confirmed that there is no problem on actual evaluation or mass-production board.
Especially, it is necessary to be ware such a behavior when the large phase-shift type 2ohm load, which is
a kind of sub-woofer for example, is connected to this IC, though such kind of speaker use is not
recommended.
