*Absolute maximum ratings are limiting values to be applied individually and beyond which the serviceability
of the circuit may be impaired. Functional operability is not necessarily implied. Exposure to absolute
maximum rating conditions for an extended period of time 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 AD6645 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!
