Notes:
2. Exceeding the absolute maximum ratings may damage the device.
3. The device is not guaranteed to function outside its operating ratings.
4. Exceeding the maximum differential input voltage will damage the input stage and degrade performance (in particular, input bias current is likely to
increase).
5. Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5kΩ in series with 100pF.
6. DC signal referenced to input. Refer to the
Typical Characteristics
section for “AC
