Data Sheet AD7262 ABSOLUTE 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 DRIVE to DGND −0.3 V to AVCC V or any other conditions above those indicated in the operational DRIVE to AGND −0.3 V to AVCC section of this specification is not implied. Operation beyond AVCC to AGND/DGND −0.3 V to +7 V the maximum operating conditions for extended periods may CA_CBVCC to CA_CB_GND −0.3 V to +7 V affect product reliability. CC_CDVCC to CC_CD_GND −0.3 V to +7 V AGND to DGND −0.3 V to +0.3 V CA_CB_GND/CC_CD_GND to DGND −0.3 V to +0.3 V
