Abstract
The position detecting apparatus includes a comparing part that compares the value of the digital signal output from the AD converter and a reference value that is based on a preset reference amplitude at the timings and outputs a control signal responsive to a result of the comparison. The position detecting apparatus includes an amplitude controlling part that controls amplification factors of the first amplifier and the second amplifier in such a manner that the value of the digital signal output from the AD converter comes closer to the reference value in response to the control signal output from the comparing part.
