AD9222ABCPZ-50

The AD9222ABCPZ-50 is an octal, 12-bit analog-to-digital converter (ADC) from Analog Devices, designed for high-performance applications requiring multiple channels. It integrates eight 12-bit ADCs with a pipelined architecture, each capable of sampling at 50 MSPS. The device provides a serial LVDS data interface with programmable clock and data alignment, supporting both ANSI-644 and reduced signal options.

Key electrical specifications include a typical signal-to-noise ratio (SNR) of 70 dB (to Nyquist), effective number of bits (ENOB) of 11.3 bits, and spurious-free dynamic range (SFDR) of 80 dBc. Linearity is excellent with typical differential nonlinearity (DNL) of ±0.3 LSB and integral nonlinearity (INL) of ±0.4 LSB. The full-power analog bandwidth is 325 MHz, and the input voltage range is 2 V p-p. The ADC operates from a 1.7V to 1.9V analog supply and features an internal reference and simultaneous sampling capability.

The device is housed in a 64-LFCSP-VQ (9x9) surface mount package and operates over a temperature range of -40°C to 85°C. Typical applications include medical imaging, nondestructive ultrasound, portable ultrasound, digital beam-forming systems, quadrature radio receivers, diversity radio receivers, tape drives, optical networking, and test equipment.
