Abstract
Various systems and methods for capturing data are disclosed. For example, some embodiments of the present invention provide methods for performing a first analog to digital conversion using a delta-sigma based analog to digital converter, and performing a second analog to digital conversion using a SAR based analog to digital converter. The delta-sigma converter provides a first portion of a conversion result, and the SAR based analog to digital converter provides a second portion of the conversion result. The methods further include combining the first portion of the conversion result with the second portion of the conversion result to produce a combined conversion result.
