AD9225

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

AD9225 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.

*Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a

stress rating only; functional operation of the device at these or any other conditions above those indicated in the

operational sections of this specification is not implied. Exposure to absolute maximum ratings for extended periods

may affect device reliability.
