Part Number: LMP90080 Hi, I'm trying to implement a 7-single ended RTD solution on my design using the LMP90080 chip. I will be using PT100 temp sensors (connected externally) and would like to drive 10mA of steady current across them. I noticed that the IC's local current sources (IB1 and IB2) can only up to 2mA (1+1). I couldn't find any reference designs for a 2 wire implementation. I have the following questions: Is there a recommended guide for a similar application? How can I effectively use the VREFP and VREFN signals in this use case? Also, what should their return paths be tied to - VIN7 maybe? Thanks!
