may cause permanent damage to the device. This is a stress Analog Inputs/Outputs rating only; functional operation of the device at these or any IN+, IN−1 to AGND VEE − 0.3 V to VCC + 0.3 V other conditions above those indicated in the operational REF, REFBUFIN, TEMP, AVDD + 0.3 V to section of this specification is not implied. Exposure to absolute REFGND to AGND AGND − 0.3 V maximum rating conditions for extended periods may affect Ground Voltage Differences device reliability. AGND, DGND, OGND ±0.3 V Supply Voltages
