SP674B

® SP574B/674B/1674B/774B 12–Bit Sampling A/D Converters s Complete Monolithic 12–Bit A/D Converters with Sample–Hold, Reference, Clock and Tri– state Outputs s Full Nyquist Sampling at All Sample Rates s Choice of Sampling Rates — 40kHz, 66kHz, 100kHz or 125kHz s Low Power Dissipation — 110mW s 12–Bit Linearity Over Temperature s Commercial, Industrial and Military Tempera- ture Ranges s Next–GenerationReplacement for574A,674A, 1674A, 774A Devices 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. They are drop–in replacements for the older 574A/ 674A/1674A/774A type devices.
