I am currently working on a research and need to work with 12 capacitors. The capacitance is small (~[0,5]pf). They are capacitors with two electrodes. Can I measure this capacitance change using ad7147? I connected bottom electrode to CINx and top electrode to GND for this purpose.
Another question is about calibration of ad7147. I know there are registers for calibration purpose to remove drift and etc. but how should I apply it? I always encounter drift in the signal.
