Analog Devices AD9258 14‑Bit Dual ADC Datasheet
The AD9258 is a dual, 14‑bit analog‑to‑digital converter designed for communications and high‑speed data‑receiver applications. It supports sample rates of 80, 105 and 125 MSPS, operates from a single 1.8 V analog supply and a separate 1.8 V digital output driver supply, and provides both CMOS and LVDS output options.
Configuration is performed via a 3‑wire SPI‑compatible serial interface, and the device includes built‑in self‑test (BIST) features, power‑down modes, and a duty‑cycle stabilizer for optimal performance across its operating range. Detailed specifications, pin descriptions, timing diagrams and design guidelines are provided throughout the document.
