Analog Devices AD9238 12‑Bit Dual ADC Datasheet
The AD9238 is a dual‑channel, 12‑bit analog‑to‑digital converter that operates from a single 3 V supply (2.7 V‑3.6 V). It offers selectable sampling rates of 20 MSPS, 40 MSPS, or 65 MSPS, low power consumption, and a clock‑duty‑cycle stabilizer for robust performance across a wide range of clock conditions.
The document provides full DC, AC, digital, and switching specifications, absolute maximum ratings, pin descriptions, typical performance characteristics, and mechanical details such as package dimensions and ordering options. Evaluation board schematics and bill‑of‑materials are also included for design reference.
