the CB designators. To order a complete evaluation kit, you will need to order the particular ADC evaluation board, e.g.,

EVAL-AD7490CB, the EVAL-CONTROL-BRD2, and a 12 V ac transformer. 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 AD7490 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.
