If you have an OpAmp based amplifier, whose open loop output impedance is Zout, and if NFB depth is D, output impedance with NFB is roughly Zout / D (D insergstesh
Sergei: In my ignorance I thought that I could not have a higher r2 value than the impedance of the following stage, which is the recorder at 20k. (where r2 isweroflu
"I'm looking at 30k for the gain setting resistor. The input impedance of the recorder is 20k, so this will not work." - why do you think it won't work ? Moresergstesh
