摘要：
A multi-bit D/A converter which improves the linearity of an analog output relative to a digital input is provided. A switch control circuit (1) turns on D some of a plurality of switches (S1 to SM) which are arranged in ascending order starting with a switch determined by a start position determination circuit (3) and turns off the remaining switches, the number of switches turned on being dependent on a digital signal (DIG). The start position determination circuit (3) sequentially changes the switches (S1, S3, S5, . . . ) serving as a selection start position to determine the selection start position for each input of the digital signal (DIG) provided in synchronism with a clock signal (CLK).
