EVAL-AD7124-4ASDZ / EVAL-AD7124-8ASDZ User Guide

The EVAL-AD7124-4ASDZ and EVAL-AD7124-8ASDZ are full-featured evaluation boards for the AD7124-4 and AD7124-8, low power, low noise, completely integrated analog front ends for high precision measurement applications. Both boards share the same PCB design.

• The AD7124-4 provides 4 differential or 7 single-ended/pseudo-differential inputs.

• The AD7124-8 provides 8 differential or 15 single-ended/pseudo-differential inputs (additional inputs on connector J4).

The evaluation boards connect to the SDP-B controller board via the 120-pin SDP connector. Power is provided through USB from the PC, with on-board regulators generating all required supply rails.

• SDP-B controller board

• USB cable

• DC signal source

• PC running Windows with a USB 2.0 port

Getting started

Warning

The evaluation software and drivers must be installed before connecting the evaluation board and controller board to the USB port of the PC, to ensure the system is correctly recognized.

1. With the SDP-B disconnected from the PC, install the AD7124 Eval+ Software. Restart the PC after installation.

2. Connect the SDP-B to the evaluation board via the 120-pin SDP connector (J3).

3. Screw the two boards together using the plastic screw and washer set included in the evaluation board kit.

4. Connect the SDP-B to the PC using a USB cable.

5. From the Start menu, navigate to Programs > Analog Devices > AD7124 Eval+ to launch the software.

6. Select EVAL-AD7124-4ASDZ or EVAL-AD7124-8ASDZ from the interface selection dialog.

See the SDP-B quickstart guide for detailed software installation and operation instructions.
