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 specification 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 specified, all other voltages
are referenced to GND.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily ac cu mu ate on
the human body and test equipment and can discharge without detection. Although the AD9995 features
proprietary ESD pro ec ion circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD pre cau ions are rec om mend ed to avoid per or mance
deg a da ion or loss of functionality.
