MilliOhmeter with 4 wires (Kelvin) Probe

Hello everyone,

I have to design a precise milliohmeter with a 4 wires probe.

I found the AD7195 that maybe is suitable for this purpose.

My questions are:

1) Is this the best IC for such this kind of application ? Other ICs ?

2) From the typical schematic, how do I connect my 4 wire probe ?

 

Thank you very much in advance

GianLuca
