* 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 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.

WARNING!

ESD SENSITIVE DEVICE

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 AD9801 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.
