Several link and switch options are incorporated in the evaluation board and should be set up before using the board. Table 2 describes the positions of the links to control the evaluation board by a PC, via the SDP-B board, using the EVAL-AD5243SDZ in single-supply mode. The functions of these link options are described in detail in Table 3 through Table 6. The evaluation board can be powered either from the SDP-B port or externally by the J1-1 and J1-2 connectors, as described in Table 1. All supplies are decoupled to ground using 10 μF tantalum and 0.1 μF ceramic capacitors. Table 2. Link Options Setup for SDP-B Control (Default) Table 1.

VA1 is the voltage applied to the A1 terminal (A20 link). VB1 is the voltage applied to the B1 terminal (A21 link). Conditions No dc offset voltage. AC signal is outside the voltage supply rails due to the dc offset voltage. DC offset voltage ≠ VDD/2.1 All other conditions. Use in conjunction with ac + dc link. All other conditions.

RW is the wiper resistance. REND-TO-END is the end-to-end resistance value. In addition, R36 can be used to achieve a pseudologarithmic attenuation. To do so, adjust the R36 resistor until a desirable transfer function is found. However, by using the R34 and R35 external resistors, the user can reduce the voltage of the voltage references. In this case, use the A1 and B1 test points to measure the voltage applied to the A0 and B0 terminals and then recalculate VA0 and VB0 in Equation 1. AC Signal Attenuation RDAC1 can be used to attenuate an ac signal, which must be provided externally using the AC_INPUT connector, as shown in Figure 3.

Additionally, clicking SHUTDOWN allows placing the RDAC in shutdown mode. When the button is clicked, the bit toggles automatically. • Rev. 0 | Page 7 of 16 SEND DATA is a customized I2C data-word that can be sent by manually switching the scroll bars from 0 to 1 or from 1 to 0, as desired, and then clicking SEND DATA. The command can contain one or two bytes, selected by BYTES TO SEND. In addition, the scroll bars are updated on each write transfer, showing the command sent to the part. Clicking EXIT closes the program but does not reset the part. A1 A1 Rev. 0 | Page 8 of 16 Figure 9.

ESD Caution ESD (electrostatic discharge) sensitive device. Charged devices and circuit boards can discharge without detection. Although this product features patented or proprietary protection circuitry, damage may occur on devices subjected to high energy ESD. Therefore, proper ESD precautions should be taken to avoid performance degradation or loss of functionality. Legal Terms and Conditions By using the evaluation board discussed herein (together with any tools, components documentation or support materials, the “Evaluation Board”), you are agreeing to be bound by the terms and conditions set forth below (“Agreement”) unless you have purchased the Evaluation Board, in which case the Analog Devices Standard Terms and Conditions of Sale shall govern. Do not use the Evaluation Board until you have read and agreed to the Agreement. Your use of the Evaluation Board shall signify your acceptance of the Agreement. This Agreement is made by and between you (“Customer”) and Analog Devices, Inc. (“ADI”), with its principal place of business at One Technology Way, Norwood, MA 02062, USA. Subject to the terms and conditions of the Agreement, ADI hereby grants to Customer a free, limited, personal, temporary, non-exclusive, non-sublicensable, non-transferable license to use the Evaluation Board FOR EVALUATION PURPOSES ONLY.

Furthermore, the license granted is expressly made subject to the following additional limitations: Customer shall not (i) rent, lease, display, sell, transfer, assign, sublicense, or distribute the Evaluation Board; and (ii) permit any Third Party to access the Evaluation Board. As used herein, the term “Third Party” includes any entity other than ADI, Customer, their employees, affiliates and in-house consultants. The Evaluation Board is NOT sold to Customer; all rights not expressly granted herein, including ownership of the Evaluation Board, are reserved by ADI. CONFIDENTIALITY. This Agreement and the Evaluation Board shall all be considered the confidential and proprietary information of ADI. Customer may not disclose or transfer any portion of the Evaluation Board to any other party for any reason. Upon discontinuation of use of the Evaluation Board or termination of this Agreement, Customer agrees to promptly return the Evaluation Board to ADI. ADDITIONAL RESTRICTIONS. Customer may not disassemble, decompile or reverse engineer chips on the Evaluation Board. Customer shall inform ADI of any occurred damages or any modifications or alterations it makes to the Evaluation Board, including but not limited to soldering or any other activity that affects the material content of the Evaluation Board. Modifications to the Evaluation Board must comply with applicable law, including but not limited to the RoHS Directive. TERMINATION. ADI may terminate this Agreement at any time upon giving written notice to Customer. Customer agrees to return to ADI the Evaluation Board at that time. LIMITATION OF LIABILITY. THE EVALUATION BOARD PROVIDED HEREUNDER IS PROVIDED “AS IS” AND ADI MAKES NO WARRANTIES OR REPRESENTATIONS OF ANY KIND WITH RESPECT TO IT.
