AD7484ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted. Stresses above those listed under Absolute Maximum Ratings Table 3. may cause permanent damage to the device. This is a stress ParameterRating rating only; functional operation of the device at these or any other conditions above those indicated in the operational AVDD to AGND −0.3 V to +7 V section of this specification is not implied. Exposure to absolute DVDD to DGND −0.3 V to +7 V maximum rating conditions for extended periods may affect VDRIVE to DGND −0.3 V to +7 V device reliability.
