This is a stress rating only; functional operation of Operating Temperature Range . –40°C to +85°C the device at these or any other conditions above those listed in the operational Storage Temperature Range . –65°C to +150°C sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Junction Temperature . 150°C
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although
WARNING!
the AD7782 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
ESD SENSITIVE DEVICE
recommended to avoid performance degradation or loss of functionality. REV. A –5–
