1Stresses above those listed under “Absolute Maximum Ratings” may
cause permanent damage to the device. This is a stress rating only and
functional operation of the device at these or any other conditions above
those listed in the operational sections of this specification is not implied.
Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.

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 the AD7276/AD7277/AD7278 feature proprietary ESD protection circuitry, perma-
nent damage may occur on devices subjected to high energy electrostatic discharges. There-
fore, proper ESD precautions are recommended to avoid performance degradation or loss of
functionality.
