5. This parameter is periodically sampled rather than 100% tested.
6. Applies to single pin only.
7. The values of external system components can change the maximum input current value, and affect operation.

A voltage drop may occur across the external source impedances of the adjacent pins, impacting conversions
on these adjacent pins. The actual maximum may need to be determined by testing the complete design.
