ADS1299: ADS1299

Ante Topic

Part Number: ADS1299

Tool/software:

Hello,

We are a team working on a project in which we want to record EEG signals and transfer them via Bluetooth/WiFi to a computer where we will process them. Therefore, we express our interest in purchasing an ADS1299: Low-Noise, 8-Channel, 24-Bit Analog-to-Digital Converter for Biopotential Measurements.
Before we proceed with the purchase, we would like to ask a few questions. First, is the ADS1299 sufficient for the entire process of collecting EEG signals from humans and transferring them to the computer? In other words, do we need any other product or software to fulfil our process or can we do it only with ADS1299?
Is it possible to expand the number of channels from eight to sixteen by combining two ADS1299 and does ADS1299 use Bluetooth to transfer the data to the computer?

    Hello Ante,

    Thank you for your interest in our ADS1299. 

    The ADS1299 is an 8-channel, 24-bit delta-sigma ADC with an integrated digital decimation filter and SPI interface. It contains all the active circuitry required to acquire EEG signals and convert them to digital. The conversion results need to be read by a host microcontroller, which would handle packaging and transmitting the data over USB, BT, Wifi, etc.

    Multiple ADS1299 devices can share an SPI bus with independent chip-select (nCS) signals, or they can be daisy-chained together. These features are described in detail in the device data sheet.

    Regards,

    Ryan

    Ryan, 

    Pl answer this for me, is there any video tutorial to setup ADS1299 EVM, I am totally new to circuits, also I am getting the below error, despite not interfacing any external host and by just seeing the scope, pl help me, also if i set in Bipolar mode and check the corresponding tp i dont see negative voltage at all, i have factory reset everything

    Hello Ryan,

    could you please send me the exact name (and product link) of the host microcontroller that would handle packaging and transmitting the data over USB, BT, Wifi, etc. that we should use with our ADS1299?

    I really appreciate any help you can provide.

    Regards,

    Ante
