| EVAL-AD5689R / EVAL-AD5687R EVALUATION BOARD One Technology Way • P.O. Box 9106 • Norwood, MA 02062-9106, U.S.A. • Tel • Fax • Preliminary Technical Document Evaluation Board for AD5689R AD5687R, Quad, 16-/12-Bit, Serial Voltage-Output Full-featured evaluation board for the AD5689R AD5687R On-board reference Various link options PC control in conjunction with Analog Devices System demonstration platform SDP PC software for control of DACs On-board ADC for voltage readback PACKAGE CONTENTS AD5689R/87R evaluation board AD5689R or AD5687R device CD that includes Self-installing software that allows users to control the board and exercise all functions of the device Electronic version of the AD5689R data sheet Electronic version of Evaluation Board Document The Analog Devices, Inc., AD5689R / AD56887R evaluation board EVAL-AD5689RSDZ and AD5687RSDZ is designed to help customers quickly prototype new AD5687R/89R circuits and reduce design time. The AD5689R/89R operates from a single V to V supply. The part incorporates an internal V on-board reference to give an output voltage span of V or 5 V. The on-board reference is on at power-up. The part must be written to after power-up to turn off the internal reference. Full data on the AD5689R/87R may be found in the data sheet available from Analog Devices and should be consulted in conjunction with this data sheet when using the evaluation board. The evaluation board interfaces to the USB port of an IBM compatible PC via the SDP board. Software is available with the evaluation board which allows the user to easily program the AD5689R/87R and simulation mode is available. This evaluation board requires the EVAL-SDP-CB1Z board. This is available on the Analog Devices website. EVAL-AD5689R / EVAL-AD5687R Application Note EVALUATION BOARD HARDWARE POWER SUPPLIES To power the AD5689R/87R evaluation board supply 6V between the +6V and AGND inputs of the evaluation board. Both AGND and DGND inputs are provided on the board. The AGND and DGND planes are connected at one location close to the AD5689R/87R. It is recommended not to connect AGND and DGND elsewhere in the system to avoid ground loop problems. All supplies are decoupled to ground with 10 µF tantalum and µF ceramic capacitors. Table Power Supply Connectors Connector No. Voltage Analog positive power supply, VDD. Digital positive power supply, VDD. +6V board positive power supply, VDD. Supply 6V for board operation. LINK OPTIONS A number of link and switch options are incorporated in the evaluation board and should be set for the required operating setup before using the board. The functions of these link options are described in detail in Table 2 describes the positions of the different links to control the evaluation board by PC, via the USB port and SDP board in single-supply mode. Table Link Options Setup for SDP Control Default Link No. Options Table Link Functions Link No. Option This Link selects the DAC analog voltage source: • Position A selects the internal voltage source from theADP3331 • Position B selects an external supply voltage EXT_VDD This Link selects the DAC digital voltage source: • Position A selects the digital voltage source from SDP board • Position B selects an external digital supply voltage EXT_VL This link selects the reference source: • • Position A selects the on-board V reference as the reference source. • Position B selects the on-board 5 V reference as the reference source. • Position C selects the internal reference as the reference source.
