Sensor device for a physical quantity and method for adjusting a sensor device for a physical quantity

2015 
There are a sensor device for a physical quantity that can output an analog output signal, wherein a characteristic variation is corrected with high accuracy, and a method for adjusting the sensor device for a physical quantity provided. An analog signal, which is input from an analog input / output section through a wire into a first conversion section is converted into digital form and set to be an initial output value of the first conversion section. The adjustment information of the first conversion section are calculated based on the deviation between the initial output value and a target output value of the first conversion section. Before an initial output value of a sensor for a physical quantity for calculating the initial setting information of a sensor device for a physical quantity is measured, the first conversion section is adjusted based on the adjustment information of the first conversion section. Also, a digital signal which is input to a second converting section is converted from a digital input / output section in analog form and set to be an initial output value of the second conversion portion. Before an output value of the sensor is issued for a physical quantity according to a digital computation in analog form, the second conversion section is adjusted based on adjustment information of the second conversion portion.
