摘要： PROBLEM TO BE SOLVED: To provide an A/D converter capable of being miniaturized even while preventing noise intrusion.
SOLUTION: The A/D converter includes: two A/D conversion blocks CB provided with a signal selection part 2 for selecting one from a plurality of inputted analog signals and outputting it and an A/D conversion part 3 for preparing digital data from the analog signal outputted from the signal selection part 2; and a data transfer block TB for outputting the digital data to an external apparatus MB. To a transmission path between the A/D conversion block CB and the data transfer block TB, an insulated transmitter 8 for transmitting data between an input end and an output end electrically insulated from each other is inserted. Each A/D conversion block CB is provided with an operation processing part 4 for executing: signal selection processing of controlling the signal selection part 2 so as to output a desired analog signal; and data output processing of transmitting the digital data prepared in the A/D conversion part 3 to the data transfer block TB by the insulated transmitter 8.
