Software www.ti.com Software Once the ADS1271EVM-PDK software (described in Step 4) is installed, evaluation and development with the ADS1271 can begin. Basic Usage Once the evaluation software is started, it checks to see whether an MMB0 is connected. If hardware is connected and recognized, the program downloads the firmware to it, and continues to operate. - Page 7 105kSPS. For other modes, it is approximately 52.5kSPS. The application will automatically reduce the data rate to the maximum allowed for that mode that is selected.
