    Stresses above those listed under Absolute Maximum Ratings may cause perma-
    nent damage to the device. This is a stress rating only; 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 AD7811/AD7812 features proprietary ESD protection circuitry, permanent damage may occur
    on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions
    are recommended to avoid performance degradation or loss of functionality.
    WARNING!
