    • Systems for determining differential and average temperatures from resistive temperature devices are provided. In one embodiment, a device comprises a bridge network including a first node and second node, wherein the first node receives a constant current from a current source; a first branch coupled between a first node and a second node, the first branch including a first temperature sensing element of a first resistive temperature device; a second branch coupled in parallel with the first branch between the first node and the second node, the second branch including a second temperature sensing element of a second resistive temperature device; a first output that provides a signal representing a difference between a voltage developed across the first temperature sensing element and a voltage developed across the second temperature sensing element; and a second output that provides a signal representing a voltage developed across first node and the second node.
