3 / 34 page www.ti.com EVM Overview 1 EVM Overview 1.1 Features ADS1148EVM/ADS1248EVM Features: • Contains all support circuitry needed for the ADS1148/ADS1248 • ±2.5V and +5V power-supply options for ADC • Voltage reference options: external or onboard • GPIO access • Compatible with the TI Modular EVM System ADS1148EVM-PDK/ADS1248EVM-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 ADS1148EVM-PDK or ADS1248EVM-PDK is available. This kit combines the ADS1148/ADS1248EVM board with the MSP430-based MMB3 motherboard, and includes ADCPro ™ software for evaluation. The MMB3 motherboard allows the ADS1148/ADS1248EVM to be connected to the computer via an available USB port. This manual shows how to use the MMB3 as part of the ADS1148EVM-PDK/ADS1248EVM-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 ADS1148EVM-PDK/ADS1248EVM-PDK is controlled by a plug-in that runs 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 ADS1148/ADS1248EVM and the ADS1148EVM-PDK/ADS1248EVM-PDK. Throughout this document, the abbreviation EVM and the term evaluation module are synonymous with the ADS1148/ADS1248EVM. For clarity of reading, the remainder of this manual will refer only to the ADS1248EVM or ADS1248EVM-PDK, but operation of the EVM and kit for the ADS1148 is identical, unless otherwise noted. 1.2 Introduction The ADS1248EVM is an evaluation module built to the TI Modular EVM System specification. It can be connected to any modular EVM system interface card. The ADS1248EVM is available as a stand-alone printed circuit board (PCB) or as part of the ADS1248EVM-PDK, which includes an MMB3 motherboard and software. As a stand-alone PCB, the ADS1248EVM is useful for prototyping designs and firmware. Note that the ADS1248EVM has no microprocessor and cannot run software. To connect it to a computer, some type of interface is required. 2 Analog Interface For maximum flexibility, the ADS1248EVM is designed for easy interfacing to multiple analog sources. Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin, dual-row, header/socket combination at J8. This header/socket provides access to the analog input pins of the ADS1248. Consult Samtec at http://www.samtec.com or call 1-800-SAMTEC-9 for a variety of mating connector options. These signals can also be connected to the terminal block J4. 3 SBAU142B – April 2009 – Revised May 2011 ADS1148EVM, ADS1248EVM, ADS1148EVM-PDK, and ADS1248EVM-PDK Submit Documentation Feedback Copyright © 2009–2011, Texas Instruments Incorporated |
