A segmented digital-to-analog converter includes: upper segments 200, 210, and 220; a thermometer decoder 400; a randomizing circuit 410 coupled between the thermometer decoder 400 and the upper segments 200, 210, and 220 for randomizing an output of the thermometer decoder 400; a divider location selector circuit 420 coupled between the randomizing circuit 410 and the upper segments 200, 210, and 220 for choosing a selected segment from the upper segments 200, 210, and 220; and lower segments 225 coupled to the selected segment.
