摘要： Provided is a temperature compensating circuit, which conducts a temperature correction having a continuous characteristic, and is small in the circuit scale. An output voltage VOUT at a connection point 14 is determined on the basis of a current Ia2, a current Ib2, and a current Ic2, and an output voltage of a temperature sensor circuit is corrected by the output voltage VOUT with a temperature. As a result, the temperature correction having the continuous characteristic is conducted on the basis of a current change of the current Ia2, the current Ib2, and the current Ic2. Because the plural temperature compensating circuits are not provided, and only one temperature compensating circuit is provided, the circuit scale becomes smaller.

摘要： Provided is a two-terminal semiconductor sensor device with which an external device having low circuit or element accuracy may be used. An output voltage (VOUT) of the two-terminal semiconductor sensor device based on temperature is not based on a constant current of a constant current source (70) of the external device and a current of an output transistor (60) of the two-terminal semiconductor sensor device, but on a resistance ratio of a voltage dividing circuit including a resistor (30) and a resistor (40), and a temperature voltage (Vbe) of the two-terminal semiconductor sensor device. Accordingly, accuracy of the constant current of the constant current source (70) of the external device that receives the output voltage (VOUT) does not need to be high. Therefore, the external device does not need to have a highly accurate circuit or element for receiving the output voltage (VOUT).
