Note: Absolute maximum rating item indicates the condition which must not be exceeded.
Application of voltage in excess of absolute maximum rating or use out absolute maximum rated temperature environment
may cause deterioration of characteristics.
*1
To use at temperature above Ta=25℃ reduce 5.52mW.
*2
To use at temperature above Ta=25℃ reduce 5mW.
*3
To use at temperature above Ta=25℃ reduce 4.7mW.
*4
To use at temperature above Ta=25℃ reduce 5.4mW.
*5
Mounted on a FR4 glass epoxy PCB(70mm×70mm×1.6mm).
*6
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.
