(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Input and output pins are diode-clamped to the internal power supplies. Limit the input current to 10 mA in the event the analog input voltage exceeds AVDD + 0.3 V or AGND – 0.3 V, or if the digital input voltage exceeds DVDD + 0.3 V or DGND – 0.3 V.
