ADCs with FIFO and Internal Reference Converter Operation The MAX11626–MAX11629/MAX11632/MAX11633 ADCs use a successive-approximation register (SAR) conversion technique and an on-chip T/H block to con- vert voltage signals into a 12-bit digital result. This sin- gle-ended configuration supports ...
