trying to figure this out, trying different thingsWhy would you ground the output of your amplifier? It's a good thing most opamps cannot supply much current or you'd have a welder.
ah your right, crap ok ill try againHow does that get you 8 kΩ input impedance?
I consulted the datasheet for that particular amplifier. Most of the opamps that you ever see besides all the ones that you won't will have a very large input impedance with respect to 8KΩ. So the question is: how can I reduce a very large impedance down to the level of 8KΩ give or take a small amount?may I ask how you know the amplifier has a input impedance of 10^12? or is that a constant for amplifiers?
