Hello, I am trying to make a simple ecg/emg acquisition circuit.
I am using 2 of these
https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/
active electrodes for the differential signal and this
https://www.olimex.com/Products/EEG/Electrodes/EEG-PE/
as a passive DRL electrode.
My supply is the 5V output of a LM7805 and I create a virtual ground at 2.5V using the TLE2426.
This
is what I have built in a breadborad.
I connect the output of the INA118 to an oscilloscope but nothing usefull is shown.
Do you see anything wrong in it?
