(Note 1) Pd is reduced by 5.4mW/°C above TA= 25°C.
(Note 2) Pd is reduced by 5.5mW/°C above TA= 25°C.
(Note 3) Pd is reduced by 5.0mW/°C above TA= 25°C.
(Note 4) Pd is reduced by 4.7mW/°C above TA= 25°C.
(Note 5) Pd is reduced by 4.5mW/°C above TA= 25°C.
(Note 6) Pd is reduced by 8.2mW/°C above TA= 25°C.
(Note 7) Pd is reduced by 6.8mW/°C above TA= 25°C.
(Note 8) Mounted on an FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).
(Note 9) Differential Input Voltage is the voltage difference between the inverting and non-inverting inputs.
The input pin voltage is set to more than VSS.
(Note 10) An excessive input current will flow when input voltages of more than VDD+0.6V or less than VSS-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.

(Note 15) Consider the power dissipation of the IC under high temperature environment when selecting the output current value.
There may be a case where the output current value is reduced due to the rise in IC temperature caused by the heat generated inside the IC.
