Hi Joerg,
it looks very nice! You've solved the problem!
But... :-)
You've only measured DC-impedance, and unfortunately we don't get
those fabulous numbers for AC.
So in the specifications we'll have to write:
Input impedance: It depends.
:-)
It will probably work quite nicely anyway, but perhaps not with
INA114 - it would be too noisy.
Regards,
Andreas
