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, dual-
channel, 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.
The evaluation board is designed to allow straightforward
customer evaluation of the device using the hardware and
software provided. 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 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 E VA L -SDP-CB1Z board
(SDP-B controller board), which is available for order on the
Analog Devices website at www.analog.com.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
The E VA L -AD5663R-SDZ and EVA L -AD5667R-SDZ
evaluation board can be powered by the J3 or J2 connector.
Supply the J3 connector with 6 V to 20 V and is regulated by
the ADP7102 low noise, complimentary metal-oxide semi-
conductor (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 µF
tantalum and 0.1 µF ceramic capacitors.

LINK OPTIONS
A number of link options are provided on the E VA L-AD5663R-
SDZ and E VA L-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.

EVALUATION BOARD SOFTWARE
INSTALLING THE SOFTWARE
The E VA L -AD5663R-SDZ and EVA L -AD5667R-SDZ
evaluation board uses the Analog Devices Analysis Control
Evaluation (ACE) software. ACE is a desktop software
application that allows the evaluation and control of multiple
evaluation systems.
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.
After the installation is finished, the E VA L-AD5663R-SDZ and
E VA L-AD5667R-SDZ evaluation board plug-ins appear when
you open ACE.
INITIAL SET UP
To set up the evaluation board, complete the following steps:
1. Connect the evaluation board to the SDP board and
connect the SDP board to the computer via a USB cable.
2. Power the evaluation board as described in the Power
Supplies section.
3. Run the ACE application. The E VA L -AD5663R-SDZ/
E VA L-AD5667R-SDZ board plug-ins appear in the
attached hardware section of the Start tab.
4. Double-click on the board plug-in to open the board view
seen in Figure 2.
5. 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.

BLOCK DIAGRAM AND DESCRIPTION
The EVA L -AD5663R-SDZ/E VA L-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.
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.

Label Function
A 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.
B 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).
C 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).
D 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.
E 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).
F 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.
G 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.
H Apply Changes: apply all modified values to the device.

MEMORY MAP
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. All changes here correspond to the block diagram;
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.
