(Note2) When operated higher than Ta=25°C, subtract 10mW per degree. (Using ROHM standard board)
(Board size: 70mm×70mm×1.6mm material: FR4 board copper foil: land pattern only)
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.
