Can anyone please suggest me any circuit or ideas as how to use these mux?

Using mux on middle wire of PT and differential dayasheet of A0 and A1 gives lead wire resistance. Do you already have an account? I will hand pick the resistors but what about temperature compensation? Then post your schematic for us to see if it is powered correctly and that the select voltage is high enough.

How to use analog multiplexer CD4051
I am only now interested in 3-wire PT sensors as these are what available locally at affordable kc. Bimpelrekkie thanks for clarifying. There is no delay needed between selecting and read or writing the pin. This i presume will help make a better differential measurement at the ADC A2 and A3 while avoiding any current passage through HC Power for Airborne Systems: Does this make sense?
If some other idea could be evolved, iic would be great! It is regarding the interfacing with an amplifier that I have connected to the further stage.
Dec 20, 6. I am guessing this should work: I am sorry, Datasheeh did not mention that in the circuit diagram, but I do have that pin grounded.
Am i wrong or OK in this regard? If i simplify the requirement to 3-wire PT, will it help? Needed accuracy must be better than 1degC and range from degC.
The daasheet not work properly with its Enable-not pin floating. As i have read in distributed posts here as well as in some papers eg. In this figure, the first wire of pt is supplied by 1mA current through a HC see footnote. Neither can i post as an edit, i guess because it is an answer of sort, a comprehensive one.
No, create an account now. However, when I interface, that the time the problem starts. If any errors or possible limitations please do let me know.
The current will always be 1 mA whatever value the resistor has.
Of course, there is no way to measure the resistance of the other two leads because no significant current passes through them. If you really want to measure ‘top’ datasneet resistance for some reason other than break protection for which A0 suffices you can add another analog multiplexer and pick off the voltage at the ‘top’ of the RTD.

Bimpelrekkie One current source for each pt is a good idea, thanks.
