AD9228 is a Quad, 12-Bit, 40/65 MSPS Serial LVDS 1.8 V A/D Converter with 4 ADCs integrated into 1 package. It has low power consumption, excellent linearity, and high signal-to-noise ratio.
The AD9228 is a quad, 12‑bit analog‑to‑digital converter designed for applications such as medical imaging, portable ultrasound, quadrature radio receivers, tape drives, and optical networking. It operates from a single 1.8 V supply and provides LVDS, CMOS, or LVPECL‑compatible serial outputs, eliminating the need for external reference or driver components.
Key features include four integrated ADCs in a 48‑lead LFCSP package, 119 mW per channel at 65 MSPS, SNR of 70 dB, ENOB of 11.3 bits, and programmable clock/data alignment with built‑in digital test pattern generation. The device supports individual channel power‑down, standby mode, and offers a data clock output up to 390 MHz for DDR operation.
