ABSTRACT:
An A/D converter includes: a plurality of A/D conversion circuits (10a,10b); an input selection section (20) for selecting the A/D conversion circuit that is not executing A/D conversion to supply analog amounts obtained by sample-holding an input signal; and an output selection section (30) for selecting the A/D conversion circuit that is not executing A/D conversion to output digital amounts obtained from the selected one. Each A/D conversion circuit includes: an input memory portion (11) for sequentially storing the supplied analog amounts in a plurality of analog memory elements (111); an A/D conversion portion (12) having a plurality of A/D conversion elements (121) for converting the analog amounts stored in the analog memory elements to digital amounts; and a shift output portion (13), having a plurality of registers (131) receiving the digital amounts from the A/D conversion elements to hold the digital amounts, for shifting and outputting the digital amounts held in the registers.
