A laboratory power supply can be connected through terminal block J14 on the MMB0, as shown in

Figure 12. Both unipolar and bipolar configurations are supported.

To use a unipolar lab power supply configuration:

• Disconnect J12 on the MMB0.

• Connect a +5V dc supply to the +5VD terminal on J14.

• Connect ground of the dc supply to the GND terminal on J14.

For bipolar mode, also connect a –10V dc supply to the –VA, and +10V on the +VA terminals on J14.

It is not necessary to connect a +5V dc supply voltage to the +5VA terminal on J14 if the +5V/+5VA

position on J13 is shorted.

Note:

The software is continually under development. These instructions and screen images are

current at the time of this writing, but may not exactly match future releases.

The program for evaluating the ADS1274EVM-PDK is called ADCPro. This program uses plug-ins to

communicate with the EVM. The ADS1274EVM-PDK plug-in is included in the ADS1274EVM-PDK

package.

The program currently runs only on Microsoft Windows platforms of Windows XP; Windows Vista is NOT

supported.

If this is the first time installing ADCPro and plug-ins, follow these procedures to run ADCPro and

complete the necessary driver installation. Make sure the ADCPro software and device plug-in software

are installed from the CD-ROM as described in Section 9.1.
