*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. T his is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may effect device reliability.

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 AD8307 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. T herefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
