may cause permanent damage to the device. This is a stress VDD to AGND −0.3 V to +7 V rating only; functional operation of the device at these or any Analog Input Voltage to AGND −0.3 V to VDD + 0.3 V other conditions above those indicated in the operational Digital Input Voltage to AGND −0.3 V to VDD + 0.3 V section of this specification is not implied. Exposure to absolute Digital Output Voltage to AGND −0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect REFIN/REFOUT to AGND −0.3 V to VDD + 0.3 V device reliability.
