When the amplification of an amplifier with feedback is given by the well-known formula A = A0(1 A0)1, it is shown that the input impedance, changed by the feedback, can be written asdoi:10.1080/00207216808938017ALEXANDERJ. W.Taylor & Francis GroupInternational Journal of Electronics...

But in OPA2192's datasheet, the differential input impedance is 100Mohm. It makes me confused about the input impedance of an amp. There is a world of difference between operation of difference amplifier and operational amplifier and for this reason they may NOT be measured the same way. I...

The input impedance of an amplifier is quoted at specified signal frequencies. The input impedance is the ratio of a small-signal input sine wave voltage across the input terminals to the current flowing into the input, at a specified frequency, or over a specified range of frequencies. Althoug...

It is thus more correct to speak of an amplifier having an input impedance rather than simply resistance, arising from the parallel combination of its input resistance and the impedance of the input capacitor. For DC and low-frequency AC signals, amplifier input impedance is dominated by the ...
