I'm planning to use the ADuCM350 to take multiple impedance measurements across an array of sensors. Ideally my sensors would represent just a resistance. However, since I'm planning to use a MOS multiplexer, I was wondering: Would the MUX stray capacitance have a significant impact on the AFE?
Since I read that the 4-wire measurement works only without isolation capacitors, I'm not certain if it's a good idea to use a MOS multiplexer or a relay array.
Thanks in advance!
