Claim 5:
6. The analog demultiplexer circuit according to claim 5, wherein the analog demultiplexer circuit is comprised in an analog-to-digital conversion system, the analog-to-digital conversion system comprising:
a first differential input type analog-to-digital converter configured to convert a first analog output signal output from the differential input/differential output type first addition circuit of the analog demultiplexer circuit into a first digital signal;
a second differential input type analog-to-digital converter configured to convert a second analog output signal output from the differential input/differential output type second addition circuit of the analog demultiplexer circuit into a second digital signal;
a folding processor configured to execute a folding processing of a third output signal of the second differential input type analog-to-digital converter with a frequency of ½ of the first clock signals as a boundary; and
a third addition circuit configured to add a fourth output signal of the first differential input type analog-to-digital converter and a fifth output signal of the folding processor.
