GENERAL DESCRIPTION

This user guide describes the operation of the EVAL-ADPD6000Z

demonstration kit, which is an evaluation module for the

ADPD6000.

The ADPD6000 is a fully integrated analog front end (AFE) for

wearable vital signal monitoring (VSM) devices. The key functions

of the ADPD6000 include photoplethysmography (PPG), electrocar-

diography (ECG), and body impedance analysis (BIA).

The demonstration kit includes both software and hardware. The

EVAL-ADPD6000Z can evaluate the AFE feature and verify the

system design based on the AFE. According to the requirements of

the application, the user can use a cable connection or Bluetooth

connection to establish communication between the PC and the

EVAL-ADPD6000Z.

This user guide also describes the example configuration of the

different functions of the ADPD6000.

For full details on the ADPD6000, see the ADPD6000 data sheet,

which must be consulted in conjunction with this user guide when

using the EVAL-ADPD6000Z.

PCB CONNECTION

Take the following steps to establish the printed circuit board (PCB)

connection:

1. Connect the battery to the connector on the EVAL-VSMUCZ

(see Figure 3. Ensure that the S1 switch is off.

Figure 3. Battery Connected to EVAL-VSMUCZ

2. Connect the EVAL-VSMUCZ to the EVAL-ADPD6000Z (see

Figure 4 and Figure 5). Ensure the EVAL-VSMUCZ and EVAL-

ADPD6000Z have the same number of pins, and that the pin

numbers match.

Figure 4. EVAL-VSMUCZ Connection

Figure 5. EVAL-ADPD6000 Connection

3. For ECG or BIA measurement, connect the EVAL-ADPD6000Z

to the electrodes on the electrode board as follows:

►For ECG measurement, connect P3 to Electrode 1, P4 to

Electrode 2, and P6 to Electrode 3. Leave Electrode 4

unconnected (see Figure 6).

►For BIA measurement, connect P3 to Electrode 1, P4 to

Electrode 2, P6 to Electrode 3, and P5 to Electrode 4 (see

Figure 7).

Note that the BIA connection can also be used for ECG meas-

urement.

SOFTWARE INSTALLATION

analog.com Rev. 0 | 5 of 20

The VSM Client software is the graphical user interface (GUI)

used for the EVAL-ADPD6000Z demonstration kit. The VSM Client

software is available on the EVAL-ADPD6000Z product page.

Take the following steps to install VSM Client:

1. Download and launch the VSM Client installer.

2. Read the software license agreement and click I Agree (see

Figure 9).

Figure 9. License Agreement

3. Select Only for me and click Next > (see Figure 10). Do not

select Anyone who uses this computer (all users), as this

option can cause the installation to suspend or fail.

Figure 10. Choose Installation Options

4. Click Browse... to choose the installation location and then click

Next > (see Figure 11).

Figure 11. Choose Installation Location

5. When the installation is complete, click Finish to complete the

installation process (see Figure 12).

POWER ON THE SYSTEM

analog.com Rev. 0 | 6 of 20

After preparing the hardware and installing the software, the EVAL-

ADPD6000Z is ready to power on.

POWER ON–CABLE CONNECTION

Connect the USB to Type-C cable from the PC to J5 on the

EVAL-VSMUCZ to power on the EVAL-VSMUCZ automatically. The

two indicator lights on the EVAL-VSMUCZ (DS1 and DS4) turn on.

If the S1 switch labeled in Figure 13 is set to on, the battery is

charged by the PC. Figure 13 shows the cable connection.

Figure 13. Cable Connection

POWER ON–BLUETOOTH CONNECTION

Take the following steps to power on the system without the USB

cable:

to on. The standalone DS1 indicator LED labeled in Figure 13

turns on.

2. Press (for about two seconds) the S3 button on the EVAL-

VSMUCZ to power on the system. The two indicator lights on

the EVAL-VSMUCZ (DS1 and DS4) turn on.

ADD DEVICE VIA BLUETOOTH

Take the following steps to add the EVAL-VSMUCZ via Bluetooth

(these steps are shown using Windows® 10):

1. Click the Bluetooth Devices icon in the system tray and select

Add a Bluetooth Device (see Figure 14).
