GENERAL DESCRIPTION

The EVAL-AD7383FMCZ is a fully featured evaluation board

that evaluates all features of the AD7383 analog-to-digital

converter (ADC). The EVAL-AD7383FMCZ is controlled by the

EVAL-SDP-CH1Z (SDP-H1) system demonstration platform

(SDP) via the 160-way SDP connector, J4. The SDP-H1

controls the EVAL-AD7383FMCZ through the USB port of a

PC using the Analysis | Control | Evaluation (ACE) software,

which is available to download from the ACE software page or the

AD7383 product page.

The EVAL-AD7383FMCZ can be used to evaluate the AD7384

(14-bit, 4 MSPS), the AD4682 (16-bit, 1 MSPS), and the AD4683

(16-bit, 500 kSPS) pseudo differential, successive approximation

in the number of clock cycles when clocking out the conversion

results, which are related to the resolution of the device. The

AD4682 and AD4683 have a slower throughput rate than the

AD7383.

For full details on the AD7383, see the AD7383 data sheet, which

must be consulted in conjunction with this user guide when using

the EVAL-AD7383FMCZ. In addition, full details on the SDP-H1

are available on the SDP-H1 product page, and the comprehensive

ACE user guide is available on the ACE software page.

Figure 1 shows the typical setup of the EVAL-AD7383FMCZ.

EVALUATION BOARD QUICK START GUIDE

The EVAL-AD7383FMCZ is powered by the SDP-H1 by default.

External power supplies can be applied to the EVAL-

AD7383FMCZ. See Table 1 for a description of the optional

external power supply connectors and Table 2 for the required

link option function descriptions. Take the following steps to

evaluate the AD7383:

1. Download and install the ACE software, which is available

on the ACE software page or the AD7383 product page.

Details of the ACE installation are available on the internal

label of the EVAL-AD7383FMCZ box. When installing the

ACE software, ensure that the SDP-H1 is disconnected

from the USB port of the PC. The PC may need to be

restarted after the installation.

2. Ensure that the link options are configured as detailed in

Table 2.

3. Connect the SDP-H1 to the EVAL-AD7383FMCZ, as

shown in Figure 2.

4. Connect the SDP-H1 to the PC via the USB cable. If

prompted by the operating system, choose to automatically

search for the SDP-H1 drivers.

5. Launch the ACE software from the following location:

C:\Program Files (x86)\Analog Devices\ACE.

6. Connect an analog signal to Channel A or Channel B of

the AD7383 via J2 for Channel A and J4 for Channel B.

The AINA− and AINB− inputs are directly connected to

VCM on the EVAL-AD7383FMCZ.

EVALUATION BOARD HARDWARE

EVAL-AD7383FMCZ DESCRIPTION

The EVAL-AD7383FMCZ is an evaluation board for the AD7383,

a 16-bit, dual, simultaneous sampling, high speed, low power,

SAR ADC with a pseudo differential input.

POWER SUPPLIES

Ensure that all link positions are set according to the required

operating mode before applying power and signals to the EVAL-

AD7383FMCZ. See Table 2 for the complete list of link options.

The EVAL-AD7383FMCZ is powered by the SDP-H1 by default.

External power supplies can be applied to the EVAL-

AD7383FMCZ. See Table 1 for a description of the optional

external power supply connectors and Table 2 for the required

link option function descriptions. The EVAL-AD7383FMCZ

has low dropout (LDO) linear regulators (the ADP7182,

ADP7104, and ADP166) that supply power to the AD7383 and

its supporting circuitry, such as the ADA4896-2 amplifiers and

the ADR4533 reference circuit. An external 2.5 V power supply

can also be used with AD7383. The EVAL-AD7383FMCZ has a

footprint ready to place an ADR4525 when an external 2.5 V

power supply is required for evaluation. A pseudo differential

signal can be connected on the Subminiature Version B (SMB)

connectors, J1 to J4.

EVALUATION BOARD SETUP PROCEDURES

The EVAL-AD7383FMCZ connects to the SDP-H1. The SDP-H1

is the communication link between the PC and the EVAL-

AD7383FMCZ. Figure 2 shows a diagram of the connections

between the EVAL-AD7383FMCZ and the SDP-H1.

Connecting the EVAL-AD7383FMCZ and the SDP-H1 to

a PC

After the ACE software is installed, take the following steps to

set up the EVAL-AD7383FMCZ and the SDP-H1.

1. Ensure that all configuration links are in the appropriate

positions, as detailed in Table 2.

2. Connect the EVAL-AD7383FMCZ to the 160-way connector

on the SDP-H1. The EVAL-AD7383FMCZ does not require

an external power supply adapter.

3. To power up the SDP-H1, insert the 12 V, dc barrel jack

(provided in the SDP-H1 kit) into the barrel connector

labeled +12V_VIN on the SDP-H1.

4. Connect the SDP-H1 to the PC via the USB cable included

in the SDP-H1 kit.

Verifying the Board Connection

After connecting the power and the USB cable from the SDP-H1

to the PC, take the following steps to verify the board connection:

1. After connecting the SDP-H1 to the PC, allow the Found

New Hardware Wizard to run. Choose to automatically

search for the drivers for the SDP-H1 if prompted by the

operating system.

2. Navigate to the Device Manager window on the PC

(see Figure 11).

3. A dialog box may open asking for permission to allow the

program to make changes to the computer. Click Yes.

4. The Computer Management window opens. From the list

labeled System Tools, click Device Manager. If the SDP-H1

driver is installed and the board is properly connected to

the PC, Analog Devices SDP-H1 is shown in the ADI

Development Tools list in the Device Manager window,

as shown in Figure 11.

23397-011

Figure 11. Device Manager Window

Disconnecting the EVAL-AD7383FMCZ

Disconnect power from the SDP-H1, or press the reset tact switch

located alongside the mini USB port on the SDP-H1, before

removing the EVAL-AD7383FMCZ from the SDP-H1.

ACE SOFTWARE OPERATION

LAUNCHING THE SOFTWARE

After the EVAL-AD7383FMCZ and SDP-H1 are properly

connected to the PC, launch the ACE software by taking the

following steps:

1. From the Start menu of the PC, select All Programs >

Analog Devices > ACE> ACE.exe to open the ACE

software main window shown in Figure 12.

2. If the EVAL-AD7383FMCZ is not connected to the USB

port via the SDP-H1 when the software launches, the

AD7383 Eval Board icon does not appear in the Attached

Hardware section in ACE (see Figure 12).To make the

AD7383 Eval Board icon appear, connect the EVAL-

AD7383FMCZ and the SDP-H1 to the USB port of the PC,

wait a few seconds, and then follow the instructions in the

dialog box that opens.

3. Double click the AD7383 Eval Board icon to open the

AD7383 Eval Board view window shown in Figure 13.

4. Double click the AD7383 chip icon in the AD7383 Eval

Board view window to open the AD7383 chip view

window shown in Figure 14.

5. Click Software Defaults and then click Apply Changes to

apply the default settings to the AD7383 (see Figure 14).

DESCRIPTION OF CHIP VIEW WINDOW

After completing the steps in the Software Installation Procedures

section and the Evaluation Board Setup Procedures section, set

up the system for data capture by taking the following steps:

1. Block icons that are dark blue are programmable blocks.

Click a dark blue block icon to open a configurable pop-up

window to customize the data capture. Figure 15 shows the

Over Sampling configurable pop-up window.

2. Click the REF block in Figure 16 to access the Reference
