Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a stress rating only; functional operation of the product at these Analog Inputs or any other conditions above those indicated in the operational IN+, IN− to GND1 −0.3 V to VREF + 0.3 V or ±130 mA section of this specification is not implied. Operation beyond Supply Voltage the maximum operating conditions for extended periods may REF, VIO to GND −0.3 V to +6 V affect product reliability. VDD to GND −0.3 V to +3 V VDD to VIO +3 V to −6 V Digital Inputs to GND −0.3 V to VIO + 0.3 V
