*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. T his 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. Only one Absolute
Maximum Rating may be applied at any one time.

CAUTIO N
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 AD7769 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. T herefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
WARNING!

O RD ERING GUID E
Do not allow VCC to exceed VDD by more than 0.3 V. In cases
where this can happen the diode protection scheme shown
below is recommended.
