(Note 8) Reduce 6.8mW per 1°C above 25°C.  
(Note 9) Mounted on an FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).  
(Note 10) Differential Input Voltage is the voltage difference between the inverting and non-inverting inputs. The input pin voltage is set to more than VEE  
.
(Note 11) An excessive input current will flow when input voltages of less than VEE-0.6V are applied.  
The input current can be set to less than the rated current by adding a limiting resistor.  
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.
