(Note 1) When mounted on standard board (70 x 70 x 1.6(mm3)), derate by 8mW/°C for Ta above25°C.
Thermal resistance θja = 125(°C/W)
Material: A FR4 grass epoxy board(3% or less of copper foil area)
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
