How can i make an amp op response faster??
Hi, i'm using an amp-op to measure a resistance of 120GOhm, yes that's correct, and my amp-op takes about 2,5 seconds to settle the signal.
How can i make it faster?
best regards, Carlos

RE: How can i make an amp op response faster??
Since this looks to be about 7 pF of node capacitance, I suggest that you look to see about minimizing the parasitic capacitance, e.g.:
Are you using a FET input op-amp?
Are you minimizing trace lengths and widths?
Are you using driven shields?
