This document presents the steps to setup an environment for using the EVAL-AD5111SDZ evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development Kit (EDK). Below is presented a picture of the EVAL-AD5111SDZ Evaluation Board with the Xilinx KC705 board.

Below is presented a picture of SDP-B Controller Board with the EVAL-AD5111SDZ Evaluation Board.

The EVAL-AD5111SDZ evaluation board is a member of a growing number of boards available for the SDP. Designed to help customers evaluate performance or quickly prototype new AD5111 circuits and reduce design time, the EVAL-AD5111SDZ evaluation board can operate in single-supply and incorporates an internal power supply powered from the USB.

The AD5111 provides a nonvolatile solution for 128-/64-/32-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient, and high bandwidth simplify open-loop applications, as well as tolerance matching applications. The new low wiper resistance feature minimizes the wiper resistance in the extremes of the resistor array to only 45 Ω, typical. A simple 3-wire up/down interface allows manual switching or high speed digital control with clock rates up to 50 MHz.
