摘要： An oscillator circuit outputs an oscillator signal with a frequency corresponding to an inductance of a displacement detector coil. An oscillation cycle measurement circuit measures a cycle of the oscillator signal output from the oscillator circuit, and outputs a signal corresponding to the measured cycle. A squaring circuit calculates and outputs a square of the signal output from the oscillation cycle measurement circuit. By the calculation and output of the square of the oscillator signal cycle, a square root component of the product of inductance and capacitance components is eliminated, so that the output signal changes linearly relative to the displacement of a displacement body. As a result, the linearity of the output signal relative to the displacement of the displacement body can be improved.

摘要： A mode detector in a sensor interface is configured to detect a mode specified by a mode signal when an input signal received from a side of a first terminal is the mode signal. A communication portion in the interface transmits an electric signal, obtained from a sensor circuit, to a side of a second terminal when a mode detected with the detector is a sensor output mode. The communication portion receives an input signal from the side of the first terminal while transmitting an output signal to the side of the second terminal, when a mode detected with the detector is a communication mode.
