GENERAL DESCRIPTION

This user guide details the operation of the evaluation board for

the AD5592R 8-channel, 12-bit, configurable analog-to-digital

converter (ADC)/digital-to-analog converter (DAC)/general-

purpose input/output (GPIO) with on-chip reference and SPI

interface.

The evaluation board is designed to help customers quickly

prototype new AD5592R circuits and reduce design time.

The AD5592R operates from a single 2.7 V to 5.5 V supply and

incorporates an internal 2.5 V reference to give an output

voltage span of 0 V to 2.5 V or 0 V to 5 V. An external reference

(a 2.5 V reference is provided on the evaluation board) can also

be used to give an output from 0 V to VREF or 0 V to 2 × VREF.

Full data on the AD5592R can be found in the data sheet,

available from Analog Devices. Consult the data sheet 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-B. Software is supplied with the evaluation board to allow

the user to program the AD5592R.

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.

GETTING STARTED

INSTALLING THE SOFTWARE

The evaluation kit for the AD5592R includes self-installing

software on a CD. The software is compatible with

Windows® XP, Windows Vista (32-bit version), and Windows 7

(32- and 64-bit versions). The software must be installed before

connecting the SDP-B board to the USB port of the PC to

ensure that the SDP-B board is recognized when it is connected

to the PC.

To install the software, take the following steps:

1. Start the Windows operating system and insert the CD.

2. The installation software opens automatically. If it does not

open automatically, run the setup.exe file from the CD.

3. After installation is complete, power up the evaluation

board as described in the Power Supplies section.

4. Connect the evaluation board to the SDP-B board, and

connect the SDP-B board into the PC using the USB cable

included in the box.

5. When the software detects the evaluation board, proceed

through any dialog boxes that appear to finalize the installation.

EVALUATION BOARD SETUP PROCEDURES

1. Connect the evaluation board to the SDP-B board, and

connect the USB cable from the SDP-B board to the PC.

2. Power the SDP-B and evaluation boards by connecting 6 V

to the J3 connector.

EVALUATION BOARD HARDWARE

POWER SUPPLIES

To use the evaluation board with the SDP-B board, a 6 V power

supply is required, which is connected to Connector J3. The

evaluation board can also be used without the SDP-B board. In

this case, Connector J2 is the power supply input for the VDD

supply.

Both the AGND and the DGND inputs are provided on the

board. The AGND and DGND planes are connected at one

location close to the AD5592R. It is recommended that AGND

and DGND not be connected elsewhere in the system to avoid

ground loop problems.

All supplies are decoupled to ground with 10 µF tantalum and

0.1 µF ceramic capacitors.

DIGITAL INPUT AND OUTPUT SIGNALS

When the SDP-B board is used to control the AD5592R

evaluation board, the digital input signals are applied to

Connector J4. When the SDP-B board is not being used, digital

signals must be applied to the 10-way header, J5.

ANALOG INPUT AND OUTPUT SIGNALS

The input/output pins of the AD5592R are available on SMB

connectors, I/O0 to I/O7. These are analog inputs or outputs

depending on whether the input/output pins are configured as

ADCs or DACs, respectively. I/O0 to I/O7 are digital inputs or

outputs if the input/output pins are configured as GPIOs.

LINK CONFIGURATION OPTIONS

A number of link options are incorporated in the evaluation

board and must be set for the required operating conditions

before using the board. The functions of these link options are

described in detail in Table 2.

SETUP CONDITIONS

Before applying power and signals to the evaluation board take

care to ensure that all link positions are set as required by the

operating mode. The evaluation board operates in two different

modes—SDP-B controlled mode and standalone mode.

The Default Position column of Table 2 shows the default

positions in which the links are set when the evaluation board is

packaged. When the board is shipped, it is assumed that the

user intends to operate the evaluation board with the SDP-B

board (SDP-B controlled mode).

Table 2. Link Functions

Link Name Option Default Position

LK1 This link selects the VDD source for the AD5592R. A

Position A selects the internal voltage source (5V_VDD) from the ADP3331.

Position B selects an external supply voltage (EXT_VDD).

LK2, LK4,

LK4-LK9,

LK20

These links connect 100 kΩ pull-down resistors from the input/output pins to AGND. When the link is

removed, the level of associated pins is determined by the configuration of the AD5592R.

LK3 This link selects the reference source for the AD5592R. A

Position A selects the on-board 2.5 V reference as the reference source.

Position B selects an off-board voltage reference via the EXT_REF connector. Select this option if the

internal reference is to be used.

LK11 This link is not used for the AD5592R. OUT

EVALUATION BOARD CIRCUITRY

The AD5592R evaluation board allows the function and

performance of the device to be easily tested. The evaluation

board contains two voltage regulators that not only generate the

analog and digital power supplies but also power the SDP-B

board if it is connected. The two regulators are powered via a

6 V supply attached to Connector J3. Alternatively, a separate

supply can be attached via Connector J2.

The SDP-B board typically controls the AD5592R and is

attached to Connector J4. The SDP-B board allows the software

provided with the kit to be used to configure the AD5592R as

well as write and read data to and from the AD5592R.

When the SDP-B is not required, the control signals can be

applied to the AD5592R by connecting them to the relevant

pins on Connector J5.

In addition to the on-chip reference of the AD5592R, an

external, 2.5 V reference is also provided and can be connected

to the VREF pin of the AD5592R using Link LK3.

HOW TO USE THE SOFTWARE

STARTING THE SOFTWARE

To run the program, do the following:

1. Connect the evaluation board to the SDP-B board,

and connect the USB cable from the SDP-B board to

the PC.

2. Power the SDP-B and evaluation boards by connecting

6 V to the J3 connector.

3. Click Start > All Programs > Analog Devices >

AD5592R >.AD5592R Evaluation Software. When

the software connects to the evaluation board, the

message shown in Figure 3 displays.

Figure 3. Connection Message

If the SDP-B board is not connected to the USB port when

the software is launched, a connectivity error displays (see

Figure 4). Simply connect the evaluation board to the USB

port of the PC, wait a few seconds, click Rescan, and follow

the instructions.

Figure 4. Connectivity Error

Alternatively, the software can be used without an evaluation

board. The software runs in simulation mode, displaying

expected outputs based on the input data. When the software

runs, the user is first prompted to configure the AD5592R

input/output pins as shown in Figure 5. The main window of

the AD5592R evaluation software then opens, as shown in

Figure 6. The user can click on the block diagram to access the

DAC, ADC, and GPIO functions, as well as other options such

as enabling the internal reference.

Figure 5. Configuration Menu

DAC TAB

The DAC tab gives the user access to the DAC functions. Each

DAC has its own numeric control where a value can be loaded

to the appropriate DAC. Clicking Update DAC Registers loads

the data appropriately as determined by the setting of the LDAC

Mode control.

ADC TAB

The ADC tab allows the user to select ADC channels on which

to perform conversions. The Repeat Sequence checkbox should

be set to take multiple samples. The user can select the number

of samples per channel and the sample frequency. Clicking Take

Samples programs the AD5592R for the desired sequence and

takes the appropriate number of samples. The data collected

from the AD5592R is split into separate channels and displayed

on the graph as voltage. The user has the option to save the data

to a comma delimited spreadsheet file.

GPIO TAB

The GPIO tab allows the user to set the output levels for pins set

as general-purpose outputs and read the levels of pins set as

general-purpose inputs.

SIMPLE CONTROLS

The simple controls tab allows the user to enter 16-bit values

directly into the Write Array control. These values can then be

written to the AD5592R by clicking the Write and Read button.

Data that appears on the SDO pin of the AD5592R is shown in

the Read Array control. Note that the data displayed in the

Read Array control will be invalid if it is not part of a read

operation from the AD5592R. Any commands sent to

the AD5592R that change the configuration of the AD5592R

will not be reflected in the other tabs.
