SP574B
SP574B is 12-Bit Sampling A/D Converters manufactured by Sipex.
DESCRIPTION
…
The SP574B/674B/1674B/774B (SPx74B) Series are plete 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 patibility with prior versions. They are drop- in replacements for the older 574A/ 674A/1674A/774A type devices.
