(Note 1) Pd should not be exceeded.

(Note 2) Mounted on 1 layer 70mm x 70mm x 1.6mm Glass Epoxy PCB (the density of copper:3%). Reduce by 7.2mW/°C for Ta over 25°C.

(Note 3) Mounted on JESD51-7. Reduce by 31.2mW/°C for Ta over 25°C.

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.
