I want to generic hardware for RTD to connect both 2 wire and 3 wire types. However I should connect 4 RTDs to one IC. I want to use PT100 and PT1000 RTD types on the same configuration. What can you advise me? Should I use analog switch IC(if it's, which one?), or different connection method? Addition of that, I want to ask a question about Rsense, should I use Rsense sharing to yield max channel number and interchangeability?
