AD7863ABSOLUTE MAXIMUM RATINGS TA = 25°C, unless otherwise noted. Table 3. Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress Parameter Ratings rating only; functional operation of the device at these or any VDD to AGND −0.3 V to +7 V other conditions above those indicated in the operational VDD to DGND −0.3 V to +7 V section of this specification is not implied. Exposure to absolute Analog Input Voltage to AGND maximum rating conditions for extended periods may affect AD7863-10 ±17 V device reliability.
