DESCRIPTION…
The SP574B/674B/1674B/774B (SPx74B) Series are complete 12–bit successive–approximation A/D converters integrated on a single die with tri-state output latches, an internal reference, clock and a sample–hold. The new “B–Series” features true Nyquist sampling while maintaining compatibility with prior versions.
