Op_amp_bridge_amplifier
In this circuit, the LM107 serves as the amplifier for two temperature sensors connected In a bridge configuration. As shown by the equations, VOUT depends on the resistance of the sensors. In turn, sensor resistance depends on temperature, so VOUT is related to temperature. See chapter 13 for additional temperature sensing and control circuits.
