The A version is fully specified up to 105°C with a maximum sample rate of 450 kSPS and I
Z = RoHS Compliant Part.
This can be used as a stand alone evaluation board or in conjunction with the Evaluation Controller Board for evaluation/demonstration purposes.
This board is a complete unit, allowing a PC to control and communicate with all Analog Devices, Inc., evaluation boards ending in the CB designators. To order a
complete evaluation kit, the particular ADC evaluation board needs to be ordered, for example, EVAL-AD7864-1CB, the EVAL-CONTROL BRD2, and a 12 V ac
transformer. See the Evaluation Board application note for more information.
