ADS1299: ADS1299

Neural Explorer
Prodigy 40 points
Part Number: ADS1299

Hi,

I'm working on both EEG and EMG setups with the ADS1299 but I'm a little confused. In EEG, each channel is taken as the differential as across the reference and the electrode, whereas in EMG it's the differential across a pair of electrodes. How does that change my layout with the ADS1299? Do I just connect all negative inputs/or all the positive inputs to the reference for EEG and not for EMG?

Additionally are there any references on using the ADS1299 for EMG vs EEG?

Thanks,

    Hi Vini,

    Welcome to the E2E forum and thank you for the post.

    The ADS1299 can be used in differential mode measurement or single-ended mode with respect to a reference signal. Please refer to Figure 72 and Figure 73 in the ADS1299 datasheet for reference. 

    Thanks
