EVALUATION BOARD FOR THE AD5545

The EVAL-AD5545SDZ is used in conjunction with an SDP1Z

system demonstration platform board available from Analog

Devices, which is purchased separately from the evaluation

board. The USB-to-SPI communication to the AD5545 is

completed using this Blackfin®-based demonstration board.

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

ADSP-BF527 processor with USB connectivity to the PC

through a USB 2.0 high speed port. For more information about

this device, see the system demonstration platform web page.

OPERATING THE EVALUATION BOARD

The evaluation board requires ±12 V and +5 V supplies.

The +12 V VDD and −12 V VSS are used to power the output

amplifier, and the +5 V is used to power the DAC (DVDD).
