ADS1174EVM/ADS1274EVM Bill of Materials

......................................................................... 28

ADS1174EVM/ADS1274EVM Features:

• Contains all support circuitry needed for the ADS1174/ADS1274

• +10V and –10V generated from the +5V supply or supplied externally

• Voltage reference options: external or onboard

• Clock options: External clock source or 27MHz onboard crystal oscillator

• GPIO access

• Compatible with the TI Modular EVM System

ADS1174EVM-PDK/ADS1274EVM-PDK Features:

• Easy-to-use evaluation software for Microsoft® Windows® XP

• 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 ADS1174EVM-PDK or ADS1274EVM-PDK is available. This kit combines

the ADS1174EVM/ADS1274EVM board with the DSP-based MMB0 motherboard, and includes ADCPro™

software for evaluation.

The MMB0 motherboard allows the ADS1174EVM/ADS1274EVM to be connected to the computer via an

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

ADS1174EVM-PDK/ADS1274EVM-PDK, but does not provide technical details about 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 ADS1174EVM-PDK/ADS1274EVM-PDK is controlled by a plug-in running in ADCPro. For

more information about ADCPro, see the ADCPro™ Analog-to-Digital Converter Evaluation Software

User's Guide (literature number SBAU128), available for download from the TI web site.

This manual covers the operation of both the ADS1174EVM/ADS1274EVM and the

ADS1174EVM-PDK/ADS1274EVM-PDK. Throughout this document, the abbreviation EVM and the term

evaluation module are synonymous with the ADS1174EVM and the ADS1274EVM. For clarity of reading,

the remainder of this manual will refer only to the ADS1274EVM or ADS1274EVM-PDK, but operation of

the EVM and kit for the ADS1174 is identical, unless otherwise noted.

The ADS1274EVM is an evaluation module built to the TI Modular EVM System specification. It can be

connected to any modular EVM system interface card.

The ADS1274EVM is available as a stand-alone printed circuit board (PCB) or as part of the

ADS1274EVM-PDK, which includes an MMB0 motherboard and related software. As a stand-alone PCB,

the ADS1274EVM is useful for prototyping designs and firmware.

Note that the ADS1274EVM has no microprocessor and cannot run software. To connect it to a computer,

some type of interface is required.
