The AD9224 is a monolithic, single supply, 12-bit, 40 MSPS, analog-to-digital converter with an on-chip, high performance sample-and-hold amplifier and voltage reference. The AD9224 uses a multistage differential CML voltage reference and ADC, and integrates high performance analog input, digital logic, and reference voltage source.
The AD9224 is a monolithic 12‑bit, 40 MSPS analog‑to‑digital converter that operates from a single +5 V supply. It integrates a high‑performance sample‑and‑hold amplifier and voltage reference, providing a straight‑binary output and an out‑of‑range indicator. The device is offered in a 28‑lead SSOP package and is pin‑compatible with the AD9220‑AD9225 family.
The datasheet includes detailed electrical specifications, absolute maximum ratings, functional block diagrams, pin descriptions, and typical performance graphs such as SINAD, THD, INL, and SFDR versus input frequency. An evaluation board layout and mechanical dimensions are also provided.
