Abstract
An A/D conversion device includes a first A/D converter that receives an analog vibration signal corresponding to a vibration detected by a vibration detecting sensor and converts the analog vibration signal to a first digital value, an analog amplifier that amplifies the analog vibration signal and outputs an amplified signal, a second A/D converter that converts the amplified signal to a second digital value, a determiner that determines whether an amplitude of the amplified signal input to the second A/D converter exceeds a range of amplitude that is convertible by the second A/D converter, and a selector that receives the first digital value and the second digital value and output one of the first and second digital values based on the determination of the determiner.
