Stresses above those listed under Absolute Maximum Ratings
Parameter Rating
may cause permanent damage to the device. This is a stress Analog Inputs rating only; functional operation of the device at these or any INx+, INx− to GND1 −0.3 V to V other conditions above those indicated in the operational REF + 0.3 V or ±10 mA Supply Voltage section of this specification is not implied. Exposure to absolute REFx, VIOx to GND −0.3 V to +6.0 V maximum rating conditions for extended periods may affect VDDx to GND −0.3 V to +3.0 V device reliability. VDDx to VIOx +3 V to −6 V
