I am creating an EEG using two AD8226 instrumentation amplifiers. The electrodes are in the middle of the forehead, and at the sides of the forehead. I want to obtain 2 channels. Is it ok to have the first amp take inputs from Left, Center, and the other amp from Center, Right?
Electrode impedance may be anywhere from 20k to 100k ohm.
I want to make sure that connecting only one of the electrodes to two amplifiers won't create problems.
There is a right leg drive.
