*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 condi-

tions 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 AD7485

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!
