Note:Absolute maximum rating item indicates the condition which must not be exceeded.

Application if voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature environment may cause

deterioration of characteristics.

(*13) The voltage difference between inverting input and non-inverting input is the differential input voltage.

Then input terminal voltage is set to more than VEE.
