... EVALUATION BOARD FOR THE DAC The evaluation board consists of an AD5429/AD5439/AD5449 DAC and a current-to-voltage amplifier, the AD8065. Included on the evaluation board reference, the ADR01. An external reference can also be applied via an SMB input. The evaluation kit consists of a CD-ROM with self-installing PC software to control the DAC. The software allows the user to write a code to the device ...
