AD9222ABCPZ-40

Overview

The AD9222ABCPZ-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 a typical Signal-to-Noise Ratio (SNR) of 70 dB. Power consumption is rated at 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 of 114 mW per channel at 65 MSPS
• 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 applications
• Quadrature and diversity radio receivers
• Optical networking equipment
• Test and measurement instruments

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm the sampling speed variant. Ensure the ordering code matches the required performance tier before procurement. Confirm RoHS compliance status through the manufacturer's current product status reports.

Selection Notes

Select this component when high channel density and low power are critical constraints. Compare against the pin-compatible AD9212 for lower resolution needs or the AD9252 for higher precision requirements. Evaluate the serial LVDS interface compatibility with the target FPGA or processor logic levels.

Part Context

This part belongs to the AD9222 family of octal ADCs designed for high-density data acquisition. It shares the same physical footprint and pinout as the AD9212 and AD9252 variants, facilitating design flexibility across different resolution requirements within the same hardware platform.

Replacement Considerations

The AD9212ABCPZ-40 serves as a pin-compatible alternative offering 10-bit resolution. The AD9252ABCPZ-40 provides a pin-compatible upgrade path with 14-bit resolution. Verify that the system timing margins accommodate any differences in latency or jitter specifications between these variants.
