(Note 3) Mounted on an FR4 glass epoxy PCB 70 mm70 mm1.6 mm (Copper foil area less than 3 %). (Note 4) The differential input voltage is the voltage difference between inverting input and non-inverting input. The input pin voltage is set to more than VSS. 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. www.rohm.com TSZ02201-0GNG2G500730-1-2 2015 ROHM Co., Ltd.
