AD9252 is a 8-channel, 14-bit, 50 MSPS, Serial LVDS, 1.8 V ADC data sheet from Analog Devices
The AD9252 is an octal, 14‑bit, 50 MSPS analog‑to‑digital converter designed for low cost, low power, and small size. It operates from a single 1.8 V supply and provides LVDS serial data output, making it suitable for medical imaging, ultrasound, and high‑speed data acquisition. Key features include 93.5 mW power per channel at 50 MSPS, 73 dB SNR, 11.87‑bit ENOB, and flexible SPI control for power‑down and test‑pattern generation. The datasheet provides full specifications, pin configurations, timing diagrams, and mechanical dimensions.
