Data Sheet AD7682/AD7689 ABSOLUTE MAXIMUM RATINGS Table 6.
Stresses at or above those listed under Absolute Maximum
Parameter Rating
Ratings may cause permanent damage to the product. This is a Analog Inputs stress rating only; functional operation of the product at these INx,1 COM GND − 0.3 V to VDD + 0.3 V or any other conditions above those indicated in the operational or VDD ± 130 mA section of this specification is not implied. Operation beyond REF, REFIN GND − 0.3 V to VDD + 0.3 V the maximum operating conditions for extended periods may Supply Voltages affect product reliability. VDD, VIO to GND −0.3 V to +7 V
ESD CAUTION
