ABSTRACT:
A semiconductor device includes: input terminals identified by channel numbers and configured to receive analog signals; analog input pads identified by pad numbers and connected with whole or part of the input terminals; a data holding section configured to hold a data of the input terminals; a channel designating section configured to generate a channel designation signal to designate one of the channel numbers; and a channel translating section configured to translate the channel number indicated by the channel designation signal into a specific one of the pad numbers based on the held data. An A/D converting section is configured to convert the analog signal inputted from the analog input pad corresponding to the specific pad number into a digital signal.
