(Note 1) Pd should not be exceeded.
(Note 2) Reduce by 7.2mW/°C for temperatures above Ta=25°C, Mounted on 70mmx70mmx1.6mm Glass Epoxy PCB.
(Note 3) Reduce by 31.2mW/°C for temperatures above Ta=25°C, Mounted on JESD51-7.
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. 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.
