Use the following steps:
1. Ensure that all of the jumpers are in their default position.
2. Ensure that all the power supplies are switched off.
3. Connect the power supply ground to any of the ground leads on the EVM board. (that is, TP1 and
TP3).
4. Connect the SPI master ground to any of the ground leads on the EVM board.
5. Connect the DC DMM ground probe to any of the ground leads on the EVM board.
6. Connect 5 V to J3A.3.
7. Connect the DC DMM signal probe to J1A.2.
8. Power on the power supplies.
9. The DC DMM should display mid-scale 1.25 V. This means that the hardware setup is working.
• If it does not, something may be wrong. Please check your connections and the jumper settings.
10. Send the SPI code 0x19FFFF using the DXP software.
11. The DC DMM should display full-scale 5 V. This means that your hardware and software setup are
working.
• If it does not, something may be wrong. Please check your digital interface implementation by
looking at the digital signals on a signal analyzer or an oscilloscope.
3 EVM Operation
3.1 DXP Software Installation
The DXP software required to use the DAC8562TEVM with the MMB0 must be downloaded from the
Texas Instruments website, which is available at www.ti.com/dxp. The software is listed under the
“Software” category in this product folder, as shown in Figure 2.
Figure 2. EVM Software Link
Once the download is complete, run the executable file and follow the installer instructions. After the DXP
software installs, copy the DAC8562T.xml file into the “Devices” directory that the installer created.
Typically located in ‘C:\Users\Public\Documents\DXP\Devices’. If you cannot find the “Devices” directory,
go the DXP install directory, typically “C:\Program Files\DXP” and open the file “DXP.ini”. Locate the line
that starts with “DXPDevices”; it will contain the location of the “Devices” directory.
