Stresses above those listed under Absolute Maximum Ratings Parameter Rating may cause permanent damage to the device. This is a stress AVDD to AGND −0.3 V to +3 V rating only; functional operation of the device at these or any DVDD to DGND −0.3 V to +3 V other conditions above those indicated in the operational AVDD to DVDD −0.3 V to +0.3 V section of this specification is not implied. Exposure to absolute VREF+ to REFGND −0.3 V to +7 V maximum rating conditions for extended periods may affect REFGND to AGND −0.3 V to +0.3 V device reliability.
