AD9222ABCPZ-50

Overview

The AD9222ABCPZ-50 is an octal, 12-bit analog-to-digital converter (ADC) operating at a maximum 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 compliant with ANSI-644 and operates on a single 1.8 V supply for both analog and digital domains. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 70.3 dB, an Effective Number of Bits (ENOB) of 11.38 bits, and a Spurious-Free Dynamic Range (SFDR) of 85 dBc. The component supports flexible bit orientation, programmable clock alignment, and individual channel power-down modes.

Feature Summary

• Integrates eight 12-bit ADC channels in a compact space-saving package to reduce system footprint.
• Features low power consumption of 114 mW per channel at the maximum sampling rate.
• Provides a Data Clock Output (DCO) supporting double data rate operation up to 390 MHz.
• Includes Serial Port Interface (SPI) control for programmable clock/data alignment and test pattern generation.

Applications

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

Procurement Notes

Verify the specific suffix -50 indicates the 50 MSPS speed grade when sourcing. Confirm the LFCSP-64 package type matches the design requirements. Check for RoHS compliance status as indicated in the ordering guide. Ensure the supplier provides the official Analog Devices datasheet Rev. F for accurate electrical specifications.

Selection Notes

Select this model for applications requiring multiple high-speed channels in a small form factor. Compare against the AD9212 for lower resolution needs or the AD9252 for higher 14-bit resolution. Consider the 325 MHz full-power analog bandwidth and 2 V p-p input range for signal compatibility. Evaluate power constraints against the 114 mW/channel dissipation at 50 MSPS.

Part Context

This component belongs to the AD9222 family of octal ADCs from Analog Devices. It shares pin compatibility with the AD9212 (10-bit) and AD9252 (14-bit) variants. The series is designed for low-cost, low-power applications where small package size is critical. The AD9222-50 variant specifically targets the 50 MSPS conversion rate requirement.

Replacement Considerations

Pin-compatible alternatives include the AD9222-40 (40 MSPS) and AD9222-65 (65 MSPS). For different resolutions, consider the AD9212 or AD9252. Verify that any substitute maintains the required 1.8 V supply voltage and LVDS output interface compatibility.
