Data SheetAD7791ABSOLUTE MAXIMUM RATINGSTable 3. (TA= 25°C, unless otherwise noted.) Parameter Rating Stresses above those listed under Absolute Maximum Ratings VDD to GND –0.3 V to +7 V may cause permanent damage to the device. This is a stress Analog Input Voltage to GND –0.3 V to VDD + 0.3 V rating only; functional operation of the device at these or any Reference Input Voltage to GND –0.3 V to VDD + 0.3 V other conditions above those listed in the operational sections Total AIN/REFIN Current (Indefinite) 30 mA of this specification is not implied. Exposure to absolute Digital Input Voltage to GND –0.3 V to VDD + 0.3 V maximum rating conditions for extended periods may affect Digital Output Voltage to GND –0.3 V to VDD + 0.3 V device reliability.
