Abstract
A signal converter circuit (,) includes an analog to digital converter (,) for converting an input analog signal into a digital signal. The circuit (,) also includes a DAC,with segment shuffler for shuffling the digital signal segments output by the analog to digital converter (,) to improve linearity of the converted digital signal. In addition, a shuffle controller (,) connected to the DAC (,) is for adaptively turning the shuffler of DAC (,) on and off based on a parameter, such as amplitude, of the input analog signal. The adaptive segment shuffling enables a lower performance data converter to be used in devices requiring a high dynamic range for converting signals over a wide range of signal amplitudes.
