Hi,

 

We are considering a circuit that was used AD7785.
You want to configure 3 pieces to connect the RTD(AIN1 (+/-), AIN2 (+/-), and AIN3 (+/-)) of the 4-wire sensor.

(excitation current source is common to three)

Is it possible the connection of the above?
If you were separated by 1 RTD and 2 RTD is better?
