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 ADM698/ADM699 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 perma-

nent damage to the device. This is a stress rating only and functional operation of

the device at these or any other conditions above those listed in the operational

sections of this specification is not implied. Exposure to absolute maximum ratings

for extended periods of time may affect device reliability.
