*Stresses above those listed under the 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.

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 AD9775 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.
