AD9222 is an octal, 12-bit, 40/50/65 MSPS serial LVDS 1.8V A/D converter. Its features include 8 ADCs integrated into 1 package, 114 mW ADC power per channel at 65 MSPS, SNR = 70 dB (to Nyquist), ENOB = 11.3 bits, SFDR = 80 dBc, excellent linearity with DNL = ±0.3 LSB (typical) and INL = ±0.4 LSB (typical), support for serial LVDS and reduced power signal options, data and frame clock outputs, 325 MHz full-power analog bandwidth, 2 V p-p input voltage range, 1.8 V supply operation, support for serial port control, full-chip and individual-channel power-down modes, flexible bit orientation, built-in and custom digital test pattern generation, programmable clock and data alignment, programmable output resolution, and standby mode.
The AD9222 is an octal, 12‑bit 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, CMOS, or LVPECL serial data interfaces, making it suitable for medical imaging, ultrasound, radio receivers, tape drives, optical networking, and test equipment.
Key features include eight integrated ADC channels, 114 mW power per channel at 65 MSPS, 70 dB SNR, 11.3‑bit ENOB, 325 MHz analog bandwidth, and flexible programmable clock and data alignment. The device is available in a RoHS‑compliant 64‑lead LFCSP package and supports individual channel power‑down and standby modes.
