DESCRIPTION… The SP86XX Series are complete, unipolar, 12-bit sampling A/D converters using state-of-the-art CMOS structures. They contain a complete 12-bit successive approximation A/D converter with internal sample/hold, reference, clock, digital interface for microprocessor control, and three-state output drivers. Power dissipation is only 90mW. AC and DC performance are completely specified. Sampling/conversion rates of 3µs, 5µs and 10µs are offered.
