I need a check and a confirmation for the design here below, where I use an ADS1248 to read 4 RTDs (PT-1000, 2-wire).
The temperature measurement range is -20ºC to +150ºC, so probably the resistor across REF1 (now with 1k) will be better 1k8 to work in full range. PT-1000 have a very short connection (less than 2 meter).
Thanks
