A segmented digital-to-analog converter circuit employs a tri-level technique to provide an output current in response to a bit code. DAC slice circuits are activated in unary fashion in response to their respective control signal, which are provided by a decoder circuit in response to the high-order bits. Each DAC slice circuit provides a binary weighted current to a summing node in response to the middle-order bits. One of the DAC slice circuits is selected to direct a portion of its total current to the input of a DAC_LOW circuit, where the input current is divided to provide a divided current to the summing node in response to the low-order bits. At certain code transitions a different DAC slice circuit is selected to provide the input current, and the previously selected DAC slice circuit redirects its total current to the summing node such that differential non-linearity errors are minimized.
