For use with a computer, the ADS1158EVM-PDK or ADS1258EVM-PDK is available. This kit combines

the ADS1158EVM/ADS1258EVM board with the DSP-based MMB0 motherboard.

The MMB0 motherboard allows the ADS1158EVM/ADS1258EVM to be connected to the computer via an

available USB port. This manual shows how to use the MMB0 as part of the

ADS1158EVM-PDK/ADS1258EVM-PDK, but does not provide technical detail on the MMB0 itself.

ADCPro is a program for collecting, recording, and analyzing data from ADC evaluation boards. It is based

on a number of plug-in programs, so it can be expanded easily with new test and data collection plug-ins.

The ADS1158EVM-PDK/ADS1258EVM-PDK is controlled by a plug-in running in ADCPro. For more

information about ADCPro, see the ADCPro

™ Analog-to-Digital Converter Evalutation Software User's

Guide (http://focus.ti.com/lit/ug/sbau128/sbau128.pdf), available for download from the TI web site.

This manual covers the operation of both the ADS1158EVM/ADS1258EVM and the

ADS1158EVM-PDK/ADS1258EVM-PDK. It does not describe the MMB0 motherboard in detail.

Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with

the ADS1158EVM/ADS1258EVM. For clarity of reading, this manual will refer only to the ADS1258EVM or

ADS1258EVM-PDK, but operation of the EVM and kit for the ADS1158 is identical, unless otherwise

noted.
