Abstract
PURPOSE: To easily obtain the conversion output with high accuracy, by providing a plurality of code signal generaotrs switching the reference voltage with different switching selection ratio and selecting and adding the output in response to the input digital signal.
CONSTITUTION: The code signal generating circuits A0∼An switch and output the common reference voltage with the switch 21 under the control of the control circuit 23. The selection ratio of the switch 21 is different in the circuits A0∼An, and output is made with the duty ratio in response to the set value of the set circuit 26. This output is made into DC at the smoothing circuit 24, converted into current at the voltage current conversion circuit 25, and DC currents I0∼In are fed to the output switches S0∼Sn. The currents I0∼In are selected to the weight and amplitude corresponding to each digit of the input digital signal and selected with the digit signal corresponding to the input signal given to the terminals t0∼tn by the switches S0∼Sn. The output of the switches S0∼Sn is added 27 to obtain converted analog signal at the output terminal 28.
