Abstract
An analog-to-digital converter configurable for converting both differential and single-ended analog signals. Charge sharing between two input capacitors and a DAC capacitor allow the full dynamic range of the ADC device to be used when full scale differential analog input signals are converted. When configured for single-ended operation, charge sharing of the half scale single-ended input analog voltage occurs between one input capacitor and the DAC capacitor to allow the full dynamic range of the ADC device to again be utilized.
