(1) The inputs are protected as shown below. Input voltage magnitudes above VA or below GND will not damage this device, provided current is limited per Note 5. However, errors in the A/D conversion can occur if the input goes above 2.6V or below GND as described in the Recommended Operating Conditions section.

(2) When the input voltage at any pin exceeds the power supplies (that is, VIN < AGND, or VIN > VA), the current at that pin should be limited to ±5 mA. The ±50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of ±5 mA to 10.
