AD9222BCPZ-40

Overview

The AD9222BCPZ-40 is an octal, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40 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. Key electrical specifications include a full-power analog bandwidth of 325 MHz, a differential input voltage range of 2 V p-p, and typical linearity performance characterized by ±0.3 LSB DNL and ±0.4 LSB INL. 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
• Features low power consumption of 114 mW per channel at maximum speed
• Provides data clock output supporting double data rate operation up to 390 MHz
• Includes SPI control for programmable clock/data alignment and test patterns

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 'BCPZ' against the manufacturer's current ordering guide to confirm pinout compatibility and RoHS compliance status. Ensure that the 40 MSPS variant matches the system timing requirements, as higher-speed versions exist within the same family. Confirm that the LFCSP-64 package thermal characteristics align with the target PCB layout design.

Selection Notes

Select this component when high channel density is required without sacrificing dynamic performance. The AD9222 offers a balance of low power and small footprint compared to discrete solutions. Consider the AD9212 or AD9252 if resolution requirements differ, as they share pin compatibility. Verify that the 325 MHz analog bandwidth meets the signal frequency needs of the application.

Part Context

The AD9222 belongs to a family of octal ADCs designed for applications requiring multiple channels in a minimal area. It serves as a central conversion unit in systems where board space is constrained. The device replaces multiple single-channel converters, simplifying layout and reducing overall system complexity while maintaining high-speed data acquisition capabilities.

Replacement Considerations

The AD9212 (10-bit) and AD9252 (14-bit) are pin-compatible alternatives within the same product family. These options allow for resolution adjustments without redesigning the PCB footprint. Verify that the specific sampling rate variants match the system clock requirements.
