(Note 2) Derating in done 3.1mW/for temperatures above Ta=25℃  
(Note 3) Derating in done 4.7mW/for temperatures above Ta=25,Mounted on 70mm×70mm×1.6mm Glass Epoxy PCB.  
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.
