Hi Michael Soldierram, The RTD input looks fine. You might need to change the component values in the filter, but that can be done experimentally once you get your prototypes since those resistors/caps are easy to change. See here for some general recommendations: https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/955466/faq-delta-sigma-adc-anti-aliasing-filter-component-selection I am not sure what you are trying to do with the pressure input - is that for a 4-20mA output pressure sensor? I see a 100ohm resistor and a single-ended measurement between AIN2 and AIN3. Note that the ADS1248 cannot make single-ended measurements with a unipolar supply, see equation 5 in the datasheet -Bryan
