OPA2188: RTD linearizzation

Part Number: OPA2188
Other Parts Discussed in Thread: TINA-TI, INA326, REF200, LM4040

Hi

I have try the using the RTD_Linearization_v7.xls model and Tina Simulator too for linearization of RTD PT1000

I have apply all value that the simulator and the calcolator give me and make the same schematic diagram

but the behaviour of the circuit is not Linear is like a Comparator and only work form o to maximum output voltage.

I have PT1000 and not PT100 that is show in the calculation model

is the same ? this calcolation can be applied to the PT1000 Too ?

Regards

Luigi
