AD9222ABCPZRL7-50

Overview

The AD9222ABCPZRL7-50 is an octal, 12-bit analog-to-digital converter (ADC) operating at a sampling rate of 50 MSPS. It integrates eight independent ADC channels within a single 64-lead LFCSP package. The device utilizes a serial LVDS interface for data output and operates on a single 1.8 V supply. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB to Nyquist, an effective number of bits (ENOB) of 11.3 bits, and a spurious-free dynamic range (SFDR) of 80 dBc. The full-power analog bandwidth is 325 MHz with a 2 V p-p differential input voltage range.

Feature Summary

• Integrates eight 12-bit ADC channels in a compact space-saving package.
• Features low power consumption of 114 mW per channel at maximum speed.
• Provides flexible bit orientation and programmable clock/data alignment via SPI.
• Includes built-in digital test pattern generation for system verification.

Applications

• Medical imaging and nondestructive ultrasound
• Portable ultrasound and digital beam-forming systems
• Quadrature radio receivers
• Optical networking

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the -50 designation matches the required 50 MSPS sampling rate. Ensure the LFCSP-64 footprint compatibility is validated against the target PCB layout. Check RoHS compliance status if environmental regulations apply to the assembly process.

Selection Notes

Select this model over the AD9222-40 or AD9222-65 based on the required 50 MSPS throughput. Consider the pin-compatible AD9212 for lower resolution needs or the AD9252 for higher 14-bit precision. Evaluate the 114 mW/channel power dissipation against thermal constraints in dense multi-channel designs.

Part Context

This component belongs to the AD9222 family of high-speed octal ADCs from Analog Devices. It shares the same physical footprint and control interface as the AD9212 and AD9252 variants, facilitating design scalability across different resolution and speed requirements within the same product line.

Replacement Considerations

The AD9222-40 and AD9222-65 are pin-compatible alternatives offering 40 MSPS and 65 MSPS speeds respectively. For higher resolution, the AD9252 provides 14-bit performance in the same package. Lower resolution needs may be met by the AD9212.
