Abstract:
A method for pre-loading a SAR ADC with an initial value for a selected range of high-order bits. If the ADC resolves at either an upper or a lower limit set by the pre-loaded value, the ADC may discard the pre-loaded value and perform a full search. Alternatively, the ADC may perform one or more “bonus steps” before giving up and performing a full search.
