D/A conversion circuit, A/D conversion circuit and electronic apparatus

摘要

A D/A conversion circuit includes a first D/A converting section which is connected with an output node, a first serial capacitor which is disposed between the output node and a first node, a second D/A converting section which is connected with the first node, and a control circuit. The first D/A converting section includes a first capacitor array section and a first switch array section. The second D/A converting section includes a second capacitor array section and a second switch array section. The control circuit performs a switch control for dynamically changing allocation of the capacitors to the respective bits of input digital data for the first switch array section of the first D/A converting section.
