ABSTRACT:
A Successive Approximation Routine converter is provided in which a comparator is responsive to an output of a first Digital to Analog Converter, and an output of a second Digital to Analog Converter and to a DAC common mode output reference voltage, and wherein the comparator provides data to a SAR controller indicating which one of the DAC outputs is greater than the other, and how a common mode voltage on the DAC outputs compares to the reference voltage. On this basis the SAR controller can add or subtract a common mode offset to the trial words being presented at a given bit trial such that both differential and common mode convergence is achieved.
