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.
*1 To use at temperature above Ta=25℃ reduce 6.2mW/℃.
*2 To use at temperature above Ta=25℃ reduce 5.0mW/℃.
*3 To use at temperature above Ta=25℃ reduce 4.7mW/℃.
*4 To use at temperature above Ta=25℃ reduce 4.5mW/℃.
*5 To use at temperature above Ta=25℃ reduce 7.0mW/℃.
*6 Mounted on a FR4 glass epoxy PCB(70mm×70mm×1.6mm).
*7 The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input pin voltage is set to more than VEE.
*8 An excessive input current will flow when input voltages of lesser than VEE-0.6V are applied.
The input current can be set to less than the rated current by adding a limiting resistor.
