EVM Overview

1 EVM Overview

1.1 Features

ADS1147EVM/ADS1247EVM Features:

• Contains all support circuitry needed for the ADS1147/ADS1247

• ±2.5V and +5V power-supply options for ADC

• Voltage reference options: external or onboard

• GPIO access

• Compatible with the TI Modular EVM System

ADS1147EVM-PDK/ADS1247EVM-PDK Features:

• Easy-to-use evaluation software for Microsoft

Windows

• Data collection to text files

• Built-in analysis tools including scope, FFT, and histogram displays

• Complete control of board settings

• Easily expandable with new analysis plug-in tools from Texas Instruments

For use with a computer, the ADS1147EVM-PDK or ADS1247EVM-PDK is available. This kit combines

the ADS1147/ADS1247EVM board with the MSP430-based MMB3 motherboard, and includes ADCPro™

software for evaluation.

The MMB3 motherboard allows the ADS1147/ADS1247EVM to be connected to the computer via an

available USB port. This manual shows how to use the MMB3 as part of the

ADS1147EVM-PDK/ADS1247EVM-PDK, but does not provide technical details about the MMB3 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 ADS1147EVM-PDK/ADS1247EVM-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 (literature number SBAU128), available for download from the TI web site.

This manual covers the operation of both the ADS1147/ADS1247EVM and the

ADS1147EVM-PDK/ADS1247EVM-PDK. Throughout this document, the abbreviation EVM and the term

evaluation module are synonymous with the ADS1147/ADS1247EVM. For clarity of reading, the rest of

this manual will refer only to the ADS1247EVM or ADS1247EVM-PDK, but operation of the EVM and kit

for the ADS1147 is identical, unless otherwise noted.

1.2 Introduction

The ADS1247EVM is an evaluation module built to the TI Modular EVM System specification. It can be

connected to any modular EVM system interface card.

The ADS1247EVM is available as a stand-alone printed circuit board (PCB) or as part of the

ADS1247EVM-PDK, which includes an MMB3 motherboard and software. As a stand-alone PCB, the

ADS1247EVM is useful for prototyping designs and firmware

Note that the ADS1247EVM has no microprocessor and cannot run software. To connect it to a computer,

some type of interface is required.
