AD9252ABCPZ-50

Overview

The AD9252ABCPZ-50 is an octal, 14-bit analog-to-digital converter 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 pipelined architecture with an on-chip sample-and-hold circuit and requires a single 1.8 V power supply for both analog and digital domains. It features serial LVDS outputs compliant with ANSI-644, providing data clock (DCO) and frame clock (FCO) signals. Key performance metrics include a signal-to-noise ratio of 73.2 dB at 2.4 MHz input frequency, a full-power analog bandwidth of 325 MHz, and a differential input voltage range of 2 V p-p. Total power dissipation is approximately 748 mW.

Feature Summary

• Integrates eight high-speed 14-bit ADCs in a compact surface-mount package to minimize board space.
• Features low power consumption per channel and supports individual channel power-down modes.
• Provides flexible serial port control for programmable clock alignment, output resolution, and test patterns.
• Includes built-in digital test pattern generation and standby mode capabilities.

Applications

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

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm performance grade and packaging details. Ensure compatibility with system requirements regarding interface standards and thermal management specifications before finalizing procurement decisions.

Selection Notes

Select this component when multiple high-resolution conversion channels are required within a constrained physical footprint. Consider the 1.8 V supply requirement and LVDS output interface compatibility with downstream processing logic. Evaluate the total power budget against the specified 748 mW dissipation for the complete octal configuration.

Part Context

This part belongs to the AD9252 family of octal ADCs from Analog Devices. It is pin-compatible with lower resolution variants such as the AD9212 (10-bit) and AD9222 (12-bit), facilitating design flexibility across different performance tiers while maintaining consistent board layout requirements.

Replacement Considerations

The AD9212 and AD9222 are pin-compatible alternatives offering 10-bit and 12-bit resolutions respectively. Verify that the reduced resolution meets system accuracy requirements if substituting these parts.
