AD9222 is an 8-channel, 12-bit, 40/50/65 MSPS serial LVDS 1.8 V A/D converter from ADI. It has high precision, low power consumption, high bandwidth, low noise and other features. It is mainly used in medical imaging and nondestructive ultrasound, portable ultrasound and digital beam forming systems, Quadra, etc.
The AD9222 is an octal, 12‑bit analog‑to‑digital converter that operates at up to 65 MSPS with a single 1.8 V supply. It integrates eight ADC channels in a compact 64‑lead LFCSP package, providing low‑power operation (114 mW per channel at 65 MSPS) and flexible serial LVDS output.
The device includes programmable clock and data alignment, digital test‑pattern generation, and individual channel power‑down. It is specified for industrial temperature range (‑40 °C to +85 °C) and is RoHS‑compliant. Detailed specifications, pin configurations, timing diagrams and application notes are provided in the data sheet.
