The AD9219 is a quad, 10-bit, 40/65 MSPS serial LVDS 1.8 V A/D converter from Analog Devices. It offers excellent linearity, low power consumption, and low distortion, and is widely used in medical imaging, nondestructive ultrasound, portable ultrasound, and digital beamforming systems.
The AD9219 is a quad, 10‑bit analog‑to‑digital converter designed for low‑cost, low‑power, and small‑size applications such as medical imaging, ultrasound, and high‑speed radio receivers. It operates from a single 1.8 V supply and provides LVDS, CMOS, or LVPECL‑compatible serial data output with a data clock up to 390 MHz.
Key features include four integrated ADCs in a 48‑lead LFCSP package, 94 mW per channel at 65 MSPS, programmable clock and data alignment, and built‑in digital test‑pattern generation. Detailed specifications cover resolution, SNR, ENOB, power dissipation, and timing parameters.
