AD9461 is a 16-bit, 130 MSPS IF sampling ADC with excellent linearity and jitter performance.
The AD9461 is a 16‑bit, 130 MSPS sampling ADC optimized for high‑performance instrumentation, medical imaging, and radar applications. It features a monolithic track‑and‑hold circuit, selectable LVDS or CMOS outputs, and on‑chip reference, requiring only 3.3 V and 5.0 V supplies.
The datasheet provides full electrical specifications, timing diagrams, absolute maximum ratings, pin configurations for the 100‑lead TQFP_EP package, and ordering information, allowing designers to integrate the converter into high‑speed data‑acquisition systems.
