A gain matching method for a single bit gain ranging analog to digital converter including selecting, in response to a gain setting, a number of gain elements to be enabled in a multi-element gain controlled array interconnected between an analog input and an analog to digital converter, and patterning the enablement of the selected number of gain elements among the gain elements for matching the gain of the analog to digital converter for a range of gain settings of the converter to reduce in-band gain error due to gain element mismatch.
