I got something working using the same differential amplifier configuration i.e, subtracting a voltage 0.9 V (this can be taken from voltage reference) and a gain of 7.8 times. The output voltage is plotted using smaller step between PT = 1000 Ohm and PT = 1600 Ohm. I guess this represents 0 degC (1000 Ohm) and 158 degC (1600 Ohm). he output voltage looks linear.
Is that circuit practically possible to make on a PCB with real components ?
How much the device characteristics of AD8397 changes itself with temperature ?
