Overview
2.1
Introduction
The ADS1299EEG-FE is intended for evaluating the ADS1299 low-power, low noise 24-bit, simultaneously
sampling, eight-channel front-end for EEG applications. The digital SPI™ control interface is provided by
the MMB0 Modular EVM motherboard (Rev. D or higher) that connects to the ADS1299EEG FE
evaluation board (Rev A). The ADS1299EEG-FE (see
) is NOT a reference design for EEG
applications; rather, its purpose is to expedite evaluation and system development. The output of the
ADS1299 yields a raw, unfiltered EEG signal.
The MMB0 motherboard allows the ADS1299EEG-FE to be connected to the computer via an available
USB port. This manual shows how to use the MMB0 as part of the ADS1299EEG-FE, 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 ADS1299EEG-FE.
