Hello all,
A professor ask,
" I would like to know and understand the computation of RTD Voltage (H3 to H13 cells of RTD_Linearization_v7.xls given in the zip). The formula uses only Vref, RTD and R1 R2 R3 R4 R5 and I have to admit I do not understand…
Part Number: OPA2188 Other Parts Discussed in Thread: TINA-TI , OPA4188 , INA333 , INA827 I have tried RTD Simulator reference design SNOA838 with replacing OPA2188 which works pretty good in simulator as well as test Circuit. When I try to Convert same…
Hello Adnan,
The input common-mode of your signal is near ground, which is outside of the linear operating region of the device. Please see the graph of input common-mode range vs. output voltage on page 4 of the data sheet (lower right corner).
So…

Hello user4541368,
I recommend searching ti.com and the web for any technical documents about RTD sensors and bridge measurement systems. I have attached a presentation made by a colleague of mine, Collin Wells, that should include just about everything…
Other Parts Discussed in Thread: OPA277 , INA118 I'm modifying the TI Precision Design for a Low Level V-to-I Converter to extend the bandwidth. Currently the design as outlined in the app note has a 1kHz bandwidth and my goal is to push that out to 100kHz…
