Abstract
A D/A conversion circuit includes a first D/A converter and a second D/A converter that respectively output a first voltage and a second voltage. An ith two-input selector among a plurality of input selectors of the first D/A converter selects a (4i+1)th input voltage or a (4i+3)th input voltage based on input data, and outputs the selected input voltage to a selector of a selector block in the subsequent stage. An ith three-input selector among a plurality of three-input selectors of the second D/A converter selects a 4ith input voltage, a (4i+2)th input voltage, or a (4i+4)th input voltage based on the input data, and outputs the selected input voltage to a selector of a selector block in the subsequent stage.
