A system for converting an analog signal to a digital codeword having N bit positions that includes a dual DAC structure having a small DAC and a large DAC. At least one comparator is coupled to the small DAC and large DAC. The small DAC performs bit trials to calculate bit positions 1 to M, and the large DAC with performs bit trial calculates bit positions M+1 to N after having been set with bit decisions from the bit trials of the small DAC.
