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C reduce 5.4mW.
*2
To use at temperature above Ta＝25C reduce 4.5mW.
*3
To use at temperature above Ta＝25C reduce 7.0mW.
*4
Mounted on a FR4 glass epoxy PCB(70mm×70mm×1.6mm).
*5
The voltage difference between inverting input and non-inverting input is the differential input voltage.
Then input pin voltage is set to more than VSS.
*6
An excessive input current will flow when input voltages of more than VDD+0.6V or lesser than VSS-0.6V are applied.
The input current can be set to less than the rated current by adding a limiting resistor.

Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.
