发明名称 TEMPERATURE COMPENSATING CIRCUIT FOR SENSOR
摘要 PROBLEM TO BE SOLVED: To provide a temperature compensating circuit for sensor capable of performing accurately temperature compensating, even using a simple circuit configuration having relatively few constituents. SOLUTION: An A-D converter 9 subtracts a correction value outputted from an offset compensating circuit 10 from the output value of a sensor 1 using a semiconductor strain gauge, divides a subtracted result by a correction value outputted from a sensitivity correcting circuit 11, analog-digital converts the divided result, and outputs a digital value. The circuit 10 outputs a correction value for an offset value of the sensor 1 responsive to an environmental temperature. And, the circuit 11 outputs a correction value for a sensitivity of the sensor 1 responsive to the environmental temperature.
