Parameter Rating
may cause permanent damage to the device. This is a stress V rating only; functional operation of the device at these or any DD to AGND −0.3 V to +7 V DV 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. Exposure to absolute DRIVE to DGND −0.3 V to DVDD V maximum rating conditions for extended periods may affect DRIVE to AGND −0.3 V to AVDD AV device reliability.
