Multiplexer EMI issues

by danielm96 on Fri Jul 17, 2020 2:44 pm

I am trying to multiplex (SparkFun PID 13906 Multiplexer) two thermistor (Anycubic NTC 3950 100K Thermistor) measurements into my Arduino Uno and I believe that the multiplexer has low resistance or I am switching the multiplexer fast enough that the voltage or current on one port is leaking into my other thermistor reading. I give 500 ms between measurements. Could it be leakage between ports?

That is a Sparkfun product. Best to ask your question on the Sparkfun forums.
