The AD9244 is a 14-bit, 40 MSPS/65 MSPS ADC that features low power, high accuracy, and high dynamic range.
The AD9244 is a monolithic, single‑supply 14‑bit ADC capable of 40 MSPS or 65 MSPS operation. It features an on‑chip sample‑and‑hold amplifier, internal voltage reference, and supports both straight‑binary and two's‑complement output formats. The device is supplied by a 5 V analog rail and a separate 3.3 V/5 V digital driver rail.
The datasheet provides detailed specifications, pin configurations, functional block diagrams, and typical application circuits. It also includes absolute maximum ratings, switching specifications, and an evaluation board bill of materials for system designers.
