The evaluation board can also be used to quickly create a prototype with the AD5663R/AD5667R, reducing design time. The AD5663R/AD5667R operate from a single 2.7 V to 5.5 V supply. Full featured evaluation board for the AD5663R and AD5667R Flexible configuration options On-board references PC control in conjunction with Analog Devices, Inc. EVAL-SDP-CB1Z system demonstration platform (SDP) PACKAGE CONTENTS EVAL-AD5663R-SDZ/EVAL-AD5667R-SDZ evaluation board GENERAL DESCRIPTION This user guide details the operation of the evaluation board for the AD5663R and the AD5667R. These are 16-bit, dualchannel, voltage output digital-to-analog converters (DACs). The AD5663R uses a serial peripheral interface (SPI) for configuration and control, whereas the AD5667R uses an I2C interface. Full data on the AD5663R/AD5667R can be found in the appropriate data sheets available from Analog Devices and should be consulted in conjunction with this user guide when using the evaluation board. The evaluation board interfaces to the USB port of a PC via the SDP board. This evaluation board requires the EVAL-SDP-CB1Z board (SDP-B controller board), which is available for order on the Analog Devices website at www.analog.com. 14544-001 AD5663R/AD5667R EVALUATION BOARD Figure 1.

Supply the J3 connector with 6 V to 20 V and is regulated by the ADP7102 low noise, complimentary metal-oxide semiconductor (CMOS) low dropout regulator (LDO). Alternatively, the J2 connector can provide power to the board, bypassing the LDOs, and is intended for use with well regulated, bench supplies. All supplies are decoupled to ground with 10 F tantalum and 0.1 F ceramic capacitors. A number of link options are provided on the EVAL-AD5663RSDZ and EVAL-AD5667R-SDZ board that must be set for the required operating conditions before using the board. Table 2 describes the positions of the links to control the evaluation board via the SDP board using a PC and external power supplies. The functions of these link options are described in detail in Table 3. Table 1.

ACE is a desktop software application that allows the evaluation and control of multiple evaluation systems. After the installation is finished, the EVAL-AD5663R-SDZ and EVAL-AD5667R-SDZ evaluation board plug-ins appear when you open ACE. 14544-002 The ACE installer installs necessary SDP drivers and .NET Framework 4 by default. Install ACE before connecting the SDP board to the USB port of the PC to ensure that the SDP board is recognized when it connects to the PC. Follow this link to download the software, and access full instructions on how to install and use this software: http://www.analog.com/ace. Figure 2. Board View of the EVAL-AD5663R-SDZ INITIAL SET UP 1. 2. 3. 4. 5. Connect the evaluation board to the SDP board and connect the SDP board to the computer via a USB cable. Power the evaluation board as described in the Power Supplies section. Run the ACE application. The EVAL-AD5663R-SDZ/ EVAL-AD5667R-SDZ board plug-ins appear in the attached hardware section of the Start tab. Double-click on the board plug-in to open the board view seen in Figure 2. The chip block diagram can be accessed by double-clicking on the AD5663R or AD5667R chip. This view provides a basic representation of functionality of the board. The main functions are labeled in Figure 3. Rev. 0 | Page 4 of 10 14544-003 To set up the evaluation board, complete the following steps: Figure 3. Chip Block Diagram view for the AD5663R UG-991 EVAL-AD5663R-SDZ/EVAL-AD5667R-SDZ User Guide BLOCK DIAGRAM AND DESCRIPTION Some of the blocks and their functions are described here as they pertain to the evaluation board. The full screen block diagram is shown in Figure 4 and Table 4 describes the functionality of each block. The EVAL-AD5663R-SDZ/EVAL-AD5667R-SDZ software is organized so that it appears similar to the functional block diagram shown in the data sheets. In this way, it is easy to correlate the functions on the board with the description in the data sheets. A full description of each block, register, and its settings is given in the AD5663R/AD5667R data sheets. H A C E G F D 14544-004 B Figure 4. Block Diagram with Labels Table 4. Block Diagram Functions Label A B C D E F G H Function Configuration wizard: used to set the initial configuration for the board. From the DAC Setup drop-down menu, the internal reference can be enabled or disabled. The reference is disabled as default. From the Power-Down Mode drop-down menu, either channel can be configured as normal operation, powered down, or in a high impedance state. After setting up the initial configuration, click Apply and the values are applied. These settings can be modified at any stage while testing. GPIO buttons: act as external GPIO pulses to the LDAC and CLR pins. The LDAC button pushes data from both input registers (D) to the DAC registers (E). The CLR button clears all data from input registers and DAC registers. These buttons are live, so there is no need to click Apply Changes (H). Command Option drop-down menu: selects how the data being transferred to the device affects the input and DAC registers. After a data value is entered in either input register (see D), this menu determine if the data is transferred to the input register only, to the channel input register and channel DAC register (E), or to the channel input register and updates both DAC registers (E). Input registers: 16-bit data word to be transferred to the device. Upon clicking the Apply Changes (H), this 16-bit data word is transferred to the device. DAC registers: inaccessible registers, displays the value that is currently present in the DAC register on the device. The DAC registers can be updated by selecting the appropriate command option or by toggling LDAC (B). Software reset: soft reset returns the board and software to default values. This button is live, so there is no need to click Apply Changes. Internal reference: selecting enabled from this setting enables the on-chip reference for the board, if disabled is selected, an external reference must be applied. Apply Changes: apply all modified values to the device. Rev. 0 | Page 5 of 10 EVAL-AD5663R-SDZ/EVAL-AD5667R-SDZ User Guide MEMORY MAP for example, if the internal register bit is enabled, it shows as enabled on the block diagram. Any bits or registers that are in bold are modified values that have not been transferred to the board. After Apply Changes is clicked, the data is transferred to the board. 14544-005 All registers are fully accessible from the memory map tab; this allows registers to be edited at a bit level. The bits shaded in dark gray are read only bits and cannot be accessed from ACE; all other bits are toggled. Apply Changes is used to transfer data to the device.
