*Minimum CLPOB pulse width is for functional operation only. Wider typical pulses are recommended to achieve low noise clamp performance.

Specifications subject to change without notice.

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

AD9945 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; functional operation of the

device at these or any other conditions outside of those indicated in the operational

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

for extended periods may affect device reliability.
