摘要： A D/A conversion circuit includes a plurality of resistors that are connected to each other in series, and a plurality of MOS transistors that are connected to terminals of the plurality of resistors, respectively. The plurality of resistors and the plurality of MOS transistors are formed on a semiconductor substrate. Each of the plurality of resistors is constituted by a resistive element and a plurality of contacts provided in the resistive element. The plurality of MOS transistors are disposed so that a plurality of virtual straight lines that pass through each of the plurality of contacts and are perpendicular to a longitudinal direction of the resistive element pass between gate electrodes of two adjacent MOS transistors, when seen in a plan view of the semiconductor substrate.

摘要： A D/A converter includes a decoder, a voltage selection circuit, and a voltage selection circuit. The voltage selection circuit includes a plurality of stages of selector blocks in which output of a selector of the selector block at the previous stage is input to a selector of the selector block at the subsequent stage. A plurality of voltages are input to the selector block at the first stage, and the selector block at the final stage outputs a D/A-converted voltage. Each of the plurality of stages of selector blocks includes a plurality of transistors and, of the plurality of transistors forming the selector block, a second transistor on a far side from a power source node is set to a lower threshold voltage than that of a first transistor on a near side from the power source node.
