Data Sheet AD7357 ABSOLUTE MAXIMUM RATINGS Table 4.
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, DGND, REFGND −0.3 V to +3 V V or any other conditions above those indicated in the operational DRIVE to AGND, DGND, REFGND −0.3 V to +5 V V section of this specification is not implied. Operation beyond DD to VDRIVE −5 V to +3 V AGND to DGND to REFGND −0.3 V to +0.3 V the maximum operating conditions for extended periods may Analog Input Voltages1 to AGND −0.3 V to VDD + 0.3 V affect product reliability.
