ADS1298R
1.2
Introduction
The ADS1298R is intended for evaluating the
low-power, 24-bit, simultaneously sampling,
eight-channel front-end for ECG and EEG applications. The digital SPI™ control interface is provided by
the MMB0 Modular EVM motherboard (Rev. C or higher) that connects to the ADS1298R ECG FE
evaluation board (Rev. A). The ADS1298R is
NOT
a reference design for ECG and EEG applications;
rather, its purpose is to expedite evaluation and system development. The output of the ADS1298R yields
a raw, unfiltered ECG signal.
The MMB0 motherboard allows the ADS1298R to be connected to the computer via an available USB
port. This manual shows how to use the MMB0 as part of the ADS1298R, but does not provide technical
details about the MMB0 itself.
Throughout this document, the abbreviation
EVM
and the term
evaluation module
are synonymous with
the ADS1298RECG-FE.
