Question about ADS1298

Andre Francisco

Hy! I'm doing an EEG/EMG project, and I need to know if it's possible to use the analogical inputs(IN1-8P) in unipolar mode, if yes can I use Right Leg Drive as a reference?

Hi Andre,

The internal RLD amplifier is a bit noisy, you may not want to use that as a reference for the EEG signals. For unipolar measurements, you could implement a common reference electrode and do a differential measurement of all electrodes against the reference electrode.
