Abstract
A multi-mode analog to digital converter is described for converting an analog input into a digital value according to a linear or a companding transfer function. The converter comprises a comparator, a successive approximation register and a charge redistribution device. The comparator compares the input voltage and a generated voltage. The successive approximation register generates a provisional binary word responsive to the output of the comparator. The charge redistribution device generates the generated voltage according to the provisional binary word and to a selected transfer function. The transfer function may be selected from the group consisting of linear and companding.
