SENSOR DEVICE |
| 摘要 |
An objective of the present invention is to provide a sensor device with an increased accuracy. In order to achieve the objective, provided is a sensor device includes: an external terminal 2 to which an external device is connected; a ground terminal 3 connected to the ground; an internal circuit 4 that generates a sensor output signal; and a protection circuit 5 having a resistive element 6 and a capacitative element 7 between the external terminal and the internal circuit, in which the capacitative element is formed of a pair of electrodes having different conductivities from each other and a lower-conductive electrode 7a of the electrodes which has a smaller conductivity is connected to the external terminal and the internal circuit. |

1. A sensor device comprising:
an external terminal to which an external device is connected; a ground terminal connected to the ground; an internal circuit that generates a sensor output signal; and a protection circuit having a resistive element and a capacitative element between the external terminal and the internal circuit, wherein the capacitative element is formed of a pair of electrodes having different conductivities from each other, and a lower-conductive electrode of the electrodes which has a smaller conductivity than the other electrode is connected to the external terminal and the internal circuit.
