Tool/software:
Hello,
following my previous thread, In my application I would like to replace the IVC102 with a discrete solution (op amp + analog switch + lower value cap).
Which part numbers (opamp and switch) does TI suggest to achieve o comparable (or even lower) total input bias current? I would like to increase, with improved component choices, the sensitivity in the 1 pA range, or so.
I think the analog switch could even be achieved with a femtoampere-leakage diode...
Thank you,
DP
