Z = RoHS Compliant Part.
The EVAL-CONTROL BRD2Z is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators. To
order a complete evaluation kit, the particular ADC evaluation board, for example, EVAL-AD7656/AD7657/AD7658CBZ, the EVAL-CONTROL BRD2Z and a 12 V
transformer must be ordered. See the relevant evaluation board technical note for more information.
