AD9222ABCPZ-65

Overview

The AD9222ABCPZ-65 is an octal, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 MSPS. It integrates eight independent ADC channels within a single 64-lead LFCSP package. The device utilizes a proprietary serial LVDS interface for data output and operates on a single 1.8 V supply. Key electrical specifications include a full-power analog bandwidth of 325 MHz, a differential input voltage range of 2 V p-p, and typical power consumption of 114 mW per channel at the maximum sampling rate.

Feature Summary

• Integrates eight 12-bit ADC channels in a compact space-saving package
• Features low power consumption with individual channel power-down capability
• 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 systems
• Portable ultrasound and digital beam-forming systems
• Quadrature and diversity radio receivers
• Optical networking equipment
• Test and measurement instruments

Procurement Notes

Verify the specific suffix designation to confirm the 65 MSPS performance grade. Ensure the ordering information matches the required package type and RoHS compliance status. Cross-reference the manufacturer's current datasheet revision to validate all electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component when high channel density and low power are critical requirements. The integrated sample-and-hold circuit and internal reference simplify design complexity. Consider the available pin-compatible family members if different resolution options are needed for future product variations or cost optimization.

Part Context

This part belongs to the AD9222 series of octal ADCs, which also includes variants supporting 40 MSPS and 50 MSPS rates. The device is designed for applications requiring multiple simultaneous conversions in a minimal footprint. It serves as a high-performance solution for dense data acquisition architectures where board space is limited.

Replacement Considerations

The AD9212 (10-bit) and AD9252 (14-bit) are pin-compatible alternatives within the same family. These substitutes offer different resolution options while maintaining the same package outline and basic functionality.
