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. REV.
