Hello As I said in a previous post I think use the 1298 for EEG. Any expert can guide me if I'm on the right track? It seems I need to implement a preamplifier. I found this scheme: http://focus.ti.com/lit/an/sbaa160a/sbaa160a.pdf Has anyone managed to do an EEG using the 1298 and say whether Am I on track? Thank you.
Intracranial EEG does not require a preamplifier since the signal strength inside the brain is sufficient. Otherwise, you should strive for a sufficiently low noise PGA such that the system contributes <2uV peak to peak noise input referred.
