I would like to use AD7193 to do open circuit detection with "BURNOUT" function of AD7193 for thermalcouple application.
Original I use the open_detect_1, but it is not much much accuracy as my expect.
I try to use open_detect_2 as pictures that does it any side effect or any others better solution for suggestion.
I have check CN0172 document that suggest using analog input R1/R2/C3(1K/1K/0.1uF) for differential Low pass filter, and C1/C2(0.01uF/0.01uF) for common-mode filtering.
Is it much better than open_detect_2?
