I'm trying to prototype a level sensor. It has base capacitance of 24pF. Dynamic range is roughly 24pF - 96pF. In addition to this I will use 30-50cm shielded cables to connect electrode. This is a floating capacitor.
I understand I need to extend the range. I would like to use EVAL-AD7746EBZ for prototyping.
Is there provision on this evaluation board to extend the range using range extension circuit?
Do I need to add parasitic capacitance due to cables to base capacitance while calculating range extension circuit parameters?
Thanks in advance,
