  • Sensor device configured to reduce output errors due to temperature characteristics
    Patent number: 11422049
    Abstract: It is desired to further reduce output errors which are caused by temperature characteristics. A sensor device is provided which includes a sense circuit which outputs a sense signal according to a magnitude of a detected physical quantity, an amplifier circuit which amplifies the sense signal, and a switching unit which switches at least one of a sensitivity of the sense circuit and an offset of the amplifier circuit discontinuously according to whether a temperature measurement value exceeds a threshold value.
    Type: Grant
