AD7265Data SheetABSOLUTE MAXIMUM RATINGS Table 3. Stresses at or above those listed under Absolute Maximum Parameter Rating Ratings may cause permanent damage to the product. This is a V stress rating only; functional operation of the product at these DD to AGND −0.3 V to +7 V DV or any other conditions above those indicated in the operational DD to DGND −0.3 V to +7 V V section of this specification is not implied. Operation beyond DRIVE to DGND −0.3 V to DVDD V the maximum operating conditions for extended periods may DRIVE to AGND −0.3 V to AVDD AV affect product reliability.
