Differential temperature sensor is used to measure temperature difference in two different area. Here is the schematic diagram of the circuit:

Differential temperature sensor circuit schematic diagram


Please note that the connection from pin 2 to pin 3 ofLM308shouldn’t be there, just break the connection so we get valid configuration like as we see in other differential amplifier. [Source: STMicroelectronics Application Note]
