I want to know the input impedance at the time of buffer ON.
For use with differential, it is good if you know the normal mode.
Assumed to have rate is 500SPS.
Sorry for late response, this was missed.
When buffer is enabled, AD7172 average input current is +/-5nA. You can calculate the input impedance based on this input current specifications. This could be around several hundreds of Megaohms.
Somebody please let me know with regards to this issue.
It has been quite sometime.
