Parameter Rating
may cause permanent damage to the device. This is a stress AV rating only; functional operation of the device at these or any DD to AGND −0.3 V to +6.5 V other conditions above those indicated in the operational DVDD to DGND −0.3 V to +6.5 V section of this specification is not implied. Exposure to absolute AGND to DGND −0.3 V to +0.3 V maximum rating conditions for extended periods may affect Analog Input Voltage to AGND −0.3 V to AVDD + 0.3 V device reliability.
