EVALUATION BOARD
The
DAC and a current-to-voltage amplifier, the AD8065. Included on
the evaluation board is a 10 V reference, the ADR01. An external
reference can also be applied via an SMB input. The evaluation kit
includes a CD-ROM with self-installing PC-based software to
control the DAC. The software allows the user to write a code to
the device and to read a code from the device.

SYSTEM DEMONSTRATION PLATFORM
The system demonstration platform (SDP) is a hardware and
software evaluation tool for use in conjunction with product
evaluation boards. The SDP board is based on the Blackfin

MICROPROCESSOR INTERFACING
The SDP is a hardware and software platform that provides a
means to communicate from the PC to Analog Devices products
and systems that require digital control and/or readback. The
