SP574B/674B/1674B/774B is a 12-bit sampling A/D converter with features such as full Nyquist sampling, multiple sampling rate options, low power dissipation, and a wide temperature range. It is the next-generation replacement for the SPx74B series.
The SP574B/674B/1674B/774B (SPx74B) Series are complete 12-bit successive-approximation A/D converters integrated on a single die. They feature an internal reference, clock, and sample-hold circuitry, offering full Nyquist sampling at rates of 40kHz, 66kHz, 100kHz, or 125kHz.
