ADS1298ECG-FE/ADS1198ECG-FE
•
The ADS1298ECG-FE/ADS1198ECG-FE should be used only by qualified engineers and technicians
who are familiar with the risks associated with handling electrical and mechanical components,
systems, and subsystems.
•
The user is responsible for the safety of themselves, fellow employees and contractors, and co-
workers when using or handling the ADS1298ECG-FE/ADS1198ECG-FE. Furthermore, the user is
fully responsible for the contact interface between the human body and electronics; consequently, the
user is responsible for preventing electrical hazards such as shock, electrostatic discharge, and
electrical overstress of electric circuit components.

Introduction
The ADS1x98ECG-FE is intended for evaluating the
and
for ECG and EEG
applications. The digital SPI™ control interface is provided by the MMB0 Modular EVM motherboard that
connects to the ADS1x98ECG FE evaluation board. The ADS1x98ECG-FE (see
) is
NOT
a
reference design for ECG and EEG applications; rather, its purpose is to expedite evaluation and system
development. The output of the ADS1298 yields a raw, unfiltered ECG signal.
The MMB0 motherboard allows the ADS1x98 to be connected to the computer via an available USB port.
This manual shows how to use the MMB0 as part of the ADS1x98ECG-FE, but does not provide technical
details about the MMB0 itself.
This document covers the operation of the ADS1x98ECG-FE evaluation system. Throughout the
document, the abbreviation
EVM
and the term
evaluation module
are synonymous with the
ADS1x98ECG-FE. For clarity of reading, this manual will refer only to the ADS1298ECG-FE or
ADS1x98ECG-FE, but operation of the ADS1198ECG-FE is identical, unless otherwise noted.
CAUTION
Many of the components on the ADS1x98ECG-FE are susceptible to damage
by electrostatic discharge (ESD). Customers are advised to observe proper
ESD handling precautions when unpacking and handling the EVM, including
the use of a grounded wrist strap, bootstraps, or mats at an approved ESD
workstation. An electrostatic smock and safety glasses should also be worn.
