DESCRIPTION鈥?/div>
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 3碌s, 5碌s and 10碌s are offered.
