Data Sheet AD8285 ABSOLUTE MAXIMUM RATINGS Table 5.
Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a Electrical stress rating only; functional operation of the product at these AVDD18x1 to GND −0.3 V to +2.0 V or any other conditions above those indicated in the operational AVDD33x2 to GND −0.3 V to +3.5 V section of this specification is not implied. Operation beyond DVDD18x3 to GND −0.3 V to +2.0 V the maximum operating conditions for extended periods may DVDD33x4 to GND −0.3 V to +3.5 V affect product reliability. Analog Inputs −0.3 V to +3.5 V
ESD CAUTION
