I want to multiplex 8 RTD sensors into a single A-to-D (e.g. AD7124). I considered the ADG707 since it has a low ΔRON.
Do you see any problem with this solution?
That is possible. In order to get better measurement results you may need to implement system calibration and compensate for the RON of the mux.
If you have not gone through it yet, please take some time to see the various solutions involving AD1724 on our website.
Please consider also posting this question to the Precision ADC forum to get more info.
