Abstract
A medical device and associated method convert an analog signal using an adaptable number of comparisons between the analog signal and a reference signal. The medical device includes an analog-to-digital (A/D) converter for receiving an analog signal. The A/D converter has a full scale range and a total number of bits spanning the full scale range. The A/D converter converts the analog signal to a digital signal over conversion cycles using an adaptable number of comparisons. For at least one of the conversion cycles, the adaptable number of comparisons is less than the total number of comparisons required to convert the analog signal over the full scale range of the A/D converter.
