ADS1248EVM-PDK Kit Operation
www.ti.com
Switch the BSL switch (SW4) on the MMB3 to the BSL position (to the left) as instructed, then press
OK. The plug-in will download the firmware to the MMB3. This operation may take a couple of minutes,
so the progress is updated in the message at the top of the ADS1248 plug-in window (as Figure 13
shows). The firmware is saved in flash memory on the MMB3, so this operation should only need to be
performed once.

Evaluating Performance with the ADCPro Software
When the firmware download completes, the message box shown in Figure 14 appears. Follow the
on-screen instructions and the plug-in should now connect to the EVM.

9 Evaluating Performance with the ADCPro Software
The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. To use
ADCPro, load an EVM plug-in and a test plug-in. To load an EVM plug-in, select it from the EVM menu.
To load a test plug-in, select it from the Test menu. To unload a plug-in, select the Unload option from the
corresponding menu.
Only one of each kind of plug-in can be loaded at a time. If you select a different plug-in, the previous
plug-in is unloaded.
9.1 Using the ADS1248EVM-PDK Plug-in
The ADS1248EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS1248. It
consists of a tabbed interface (see Figure 16), with different functions available on different tabs. These
controls are described in this section.
You can adjust the ADS1248EVM settings when you are not acquiring data. During acquisition, all
controls are disabled and settings may not be changed.
When you change a setting on the ADS1248EVM plug-in, the setting immediately updates on the board.
Settings on the ADS1248EVM correspond to settings described in the ADS1248 data sheet (available for
download at www.ti.com) for details.
The ADS1248EVM-PDK plug-in has a tabbed interface, with five different tabs to control the functions of
the ADS1248. These tabs are described below.

9.1.1 I/O Config Tab
This tab is the primary tab that controls the function of the multiplexer in the ADS1248. Recall that the
ADS1248 multiplexer is configured as shown in Figure 15. By default, all channels are set as analog
inputs; the IDACs are not routed to any channel and the IDAC controls are disabled. These controls are
enabled when the correct IDAC settings are made on the Power & Ref tab (see Section 9.1.3).
Figure 15. ADS1248 Multiplexer
The radio buttons at the far right of the panel (see Figure 16) select which pair of inputs are connected to
the PGA. Note that you may select the same input for both the positive (AINP) and negative (AINN) input;
this configuration is often selected to perform a noise test on the ADC itself.
