Abstract
An A/D converter comprises: a differential amplifier row for amplifying differential voltages between an analog input voltage and reference voltages; a first sample/hold circuit row for sampling/holding the individual differential voltages amplified; a second sample/hold circuit having a pair of second and third sample/hold circuits connected in parallel to each output of the first sample/hold circuit row, thereby performing alternate sampling; a plurality of comparators for determining whether the individual differential voltages held by the first sample/hold circuit row are positive or negative; and an encoder for outputting digital code corresponding to the outputs of the comparators.
