*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 listed in the operational sections of
this specication is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability. Absolute maximum ratings apply
individually only, not in combination. Unless otherwise specied, all other voltages
are referenced to GND.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily accumulate on
the human body and test equipment and can discharge without detection. Although the AD9991 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.
