AD7984 Data Sheet ABSOLUTE MAXIMUM RATINGS Table 5.
Stresses above those listed under Absolute Maximum Ratings
Parameter Rating
may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any Analog Inputs other conditions above those indicated in the operational IN+, IN− to GND1 −0.3 V to VREF + 0.3 V or ±130 mA section of this specification is not implied. Exposure to absolute Supply Voltage maximum rating conditions for extended periods may affect REF, VIO to GND −0.3 V to +6.0 V device reliability. VDD to GND −0.3 V to +3.0 V VDD to VIO +3 V to −6 V
