AD7171: voltage exitation for thermistor

Hi,

I proposed the following circuit to our customer for thermistor input.

     Requirment: cost, simple circuit, about 16bit p-p resolutions.

On the other hand, in Maxim's application note,

The same voltage excitation, but the connection is different.

 

(Question)

Are there advantages and disadvantages in each method?
I think MAXIM's method has a wider dynamic range and ADI's method is high precision.

Please advise me to make the best suggestions for customers.

 

Best regards,

Hiroshi
