Hello all - I am measuring tiny electrical signals in plants typically between 20mv and 160mv so +/-1v per analogue input. I have built an op amp to get the input inpedance right . My questions are what is the overall sampling rate for the arduino due and how many kb/s can I have per analogue input …

You should be able to acquire and transfer 1MS/s with the Due.
