Note 1.
Note 2.
Note 3.
Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is
likely to change).
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
Output swing limited by the maximum output sink capability, refer to the short-circuit current vs. temperature graph in
Typical Characteristics.
