may cause permanent damage to the device. This is a stress AVDD to GND −0.3 V to +30 V rating only; functional operation of the device at these or any AVSS to GND +0.3 V to −28 V other conditions above those indicated in the operational AVDD to AVSS −0.3 V to +58 V section of this specification is not implied. Exposure to absolute DVCC to GND −0.3 V to +7 V maximum rating conditions for extended periods may affect VSENSE+ to GND AVSS to AVDD device reliability. VSENSE− to GND ±5.0 V
