Abstract
A temperature compensating circuit having a third temperature sensor element for detecting an ambient temperature disposed on the same substrate on which first and second temperature sensor elements are located, and a voltage across the third sensor element, generated by supplying a current thereto, is applied to the first and second sensor elements. Therefore, a voltage applied to first and second sensor elements is automatically changed corresponding to change in ambient temperature, and accordingly a difference in temperature between first and second sensor elements can be precisely detected in a form of voltage signal.
