AD9219ABCPZRL7-40

Overview

The AD9219ABCPZRL7-40 is a quad, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40 MSPS. It integrates four pipeline ADCs with on-chip sample-and-hold circuits in a single package. The device utilizes a serial LVDS interface for data output and operates from a single 1.8 V supply. Key electrical specifications include a differential input voltage range of 2 V p-p, an analog bandwidth of 315 MHz, and a typical SNR of 61.2 dB. It features programmable clock alignment, flexible bit orientation, and individual channel power-down modes.

Feature Summary

• Integrates four independent 10-bit ADC channels within a compact LFCSP package to minimize board space.
• Provides low power consumption per channel while maintaining high dynamic performance metrics such as SNR and SFDR.
• Includes a serial port interface for configuration control, allowing programmable data alignment and test pattern generation.

Applications

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

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing components. Confirm that the -40 designation corresponds to the 40 MSPS speed grade rather than the 65 MSPS variant. Ensure compatibility with the required 48-lead LFCSP footprint during procurement planning.

Selection Notes

Select this component when a quad-channel architecture is required to reduce system complexity. Compare against the AD9219ABCPZ-65 if higher throughput up to 65 MSPS is necessary. Evaluate power constraints against the 94 mW per channel specification at maximum speeds.

Part Context

This part belongs to the AD9219 family of high-speed data converters. It shares pinout compatibility with other members like the AD9287, AD9228, and AD9259, which offer different resolutions. The device is designed for applications requiring multiple synchronized conversion channels in a small form factor.

Replacement Considerations

The AD9219ABCPZ-40 is a tray-packaged equivalent with identical electrical characteristics. For higher speed requirements, the AD9219ABCPZ-65 serves as a functional upgrade within the same package.
