Hello,
I don't have a schematic drawing of it but refer to Figure 71 Topology #2 in the datasheet and connect the two RTDs as described below:
RTD1: RLINE1 to IB1 and VIN0, RLINE2 to VIN1, RLINE2/RREF to VREFP1 and VIN2, and RREF to VREFN1. RTD1 uses VREFP1-VREFN1 for its reference.
RTD2: RLINE1 to IB2 and VIN3, RLINE2 to VIN4, RLINE2/RREF to VIN6/VREFP2, and RREF to VIN7/VREFN2. RTD2 uses VREFP2-VREFN2 for its reference.
