Rollover operative digital to analog converter (DAC). With respect to a codeword that is provided to a DAC, a processing module (e.g., a rollover processor) operates to compare the codeword to threshold(s) in accordance with adaptively partitioning the codeword into one or more sub-codewords when the codeword has a magnitude greater than at least one of the thresholds. In instances that the codeword is less than a threshold, the codeword may be provided directly to a DAC for use in generating a first analog signal. However, if the codeword is a larger than a threshold, then that portion of the codeword which is greater than the threshold may be provided to an alternative component such as one or more auxiliary or additional DACs, one or more other circuitry components, etc. in accordance with generating at least one additional analog signal to be combined with the first analog signal.
