NOTES
1 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 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.
2 Transient currents of up to 100 mA will not cause SCR latch up.

NOTES
1This can be used as a standalone evaluation board or in conjunction with the evaluation board controller for evaluation/demonstration purposes.
2This evaluation board controller is a complete unit, allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB design ators.
To order a complete evaluation kit, the particular ADC evaluation board, e.g., EVAL-AD7866CB, the EVAL-CONTROL BRD2, and a 12 V transformer must be
ordered. See relevant Evaluation Board Technical note for more information.
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
AD7866 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.
