Abstract
A digital-to-analogue converting circuit includes a driver leg having a plurality of resistance elements between a power supply voltage terminal and a ground voltage terminal, wherein at least one of the plurality of resistance elements is a variable resistor, and a code level changing unit for outputting a level-changed code to a control terminal of the variable resistor based on an activation of a digital code, wherein the level-changed code is produced by converting a level of the digital code.
