(Note 1) Reduce by 25.6mW/°C for Ta above 25°C when mounted on a 4 layer 70mm x 70mm x 1.6mm glass epoxy PCB
(Note 2) Value per channel. Set within the given range in order to not exceed the package power dissipation.
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection
measures such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
