Datasheet AD7790 (Analog Devices) - 8

Data Sheet AD7790 ABSOLUTE MAXIMUM RATINGS Table 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. Operating Temperature Range –40°C to +105°C Storage Temperature Range –65°C to +150°C
