      I simulated the ADA4805 using a source impedance of 500kohms and a voltage divider on the input with an impedance of 1meg in parallel with 1 meg (500kohms). The resulting waveform showed a signal of exactly half of the original, indicating the 260kohm differential input impedance listed on the datasheet …

      Hi Achim Thanks for your comments. Hi pcbguitar As mentioned by Achim, the op-amp differential input resistance are tied between the inverting and non-inverting input (not input to ground) so it does not go parallel with your R7. Here's an app note for your reference: https://www …
