Re: Olimex Active Electrode Input Impedance

​Mark,

Is this it?

https://www.olimex.com/Products/EEG/Electrodes/EEG-AE/resources/EEG-AE.pdf

It appears that the input impedance is going to be the non-inverting input
impedance of the TL062CD ​

​Please see page 6 of this doc

http://www.ti.com/lit/ds/symlink/tl062a.pdf

Look for "input resistance" value.  It's quite high at 10^12.  I think
that's 1Tera ohm.​




Kind regards,

Greg Feneis
