PURPOSE: An analog-to-digital converter with reduced noise is provided to change an analog signal into a digital signal by applying resolution suitable for a noise level of an analog signal. CONSTITUTION: A determination unit(11) is used to determine each noise level of a plurality of analog signals to be inputted. A setting unit(12) is used to respectively set resolution suitable for a noise level of the determined signal through the determination unit. A conversion unit(13) changes a corresponding analog signal into a digital signal according to the resolution set by the setting unit. The conversion unit changes the analog signal into the digital signal by individually applying the resolution to the plurality of analog signals to be inputted. |
