1.1 Features

ADS7953EVM/ADS7957EVM/ADS7961 EVM Features:

• Contains all support circuitry needed for the ADS7953/ADS7957/ADS7961

• Voltage reference options: external or onboard

• Buffer options: onboard analog input buffer can be bypassed

• GPIO access with HI or LO alarm options to interrupt host processor

• Compatible with the TI Modular EVM System

ADS7953EVM/ADS7957EVM/ADS7961EVM-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 ADS79xxEVM Performance Demonstration Kit (PDK) is available. This kit

combines the ADS7953EVM, ADS7957EVM or ADS7961EVM board with the TMS320VC5507

DSP-based MMB0 motherboard, and includes ADCPro™ software for evaluation.

The MMB0 motherboard allows the ADS79xxEVM to be connected to the computer via an available USB

port. This manual shows how to use the MMB0 as part of the ADS79xxEVM-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 ADS79xxEVM-PDK is controlled by a plugin running in ADCPro. For more information about ADCPro,

see the ADCPro Analog-to-Digital Converter Evalutation Software Users Guide, available for download

from the TI website.

This manual covers the operation of all three ADS7953, ADS7957 and ADS7961 devices refered to as the

ADS79xxEVM and the ADS79xxEVM-PDK. Throughout this document, the abbreviation EVM and the term

evaluation module are synonymous with the ADS79xxEVM. For clarity of reading, the rest of this manual

will refer only to the ADS7953EVM or ADS7953EVM-PDK. The individual kit contains one ADS7953EVM,

ADS7957EVM or ADS7961EVM, but operation of the EVM and kit for the ADS7957 or ADS7961 is

identical, unless otherwise noted.

1.2 Introduction

The ADS7953EVM is an evaluation module built to the TI Modular EVM System specification. It can be

connected to any of the modular EVM system interface cards available from Texas Instruments.

The ADS7953EVM is available as a stand-alone printed circuit board (PCB) or as part of the

ADS7953EVM-PDK, which includes an MMB0 motherboard and software. As a stand-alone PCB, the

ADS7953EVM is useful for prototyping designs and firmware.

Note that the ADS7953EVM has no microprocessor and cannot run software. To connect it to a computer,

some type of host processor interface capable of generating the necessary control signals is required.
