AD9273BSVZRL-40

Overview

The AD9273BSVZRL-40 is an octal analog-to-digital converter (ADC) integrated with low noise preamplifiers (LNA), variable gain amplifiers (VGA), and antialiasing filters (AAF). It features a 12-bit resolution operating at a sampling rate of 40 MSPS. The device provides single-ended inputs with a maximum input range of 733 mV p-p to 367 mV p-p depending on LNA gain settings. Key performance metrics include a signal-to-noise ratio (SNR) of 64 dB and a total power dissipation of 996 mW in full-channel mode. It utilizes serial LVDS outputs and supports SPI programming for configuration.

Feature Summary

• Integrated 8-channel pipeline ADC with LNA, VGA, and AAF
• 12-bit resolution at 40 MSPS sampling rate
• Signal-to-noise ratio (SNR) of 64 dB typical
• Total power dissipation of 996 mW in full-channel mode

Applications

• Medical imaging/ultrasound
• Automotive radar

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging when sourcing components. Confirm that the -40 speed grade matches the required 40 MSPS sampling frequency for the target application design. Ensure compatibility with the 100-lead TQFP package dimensions during PCB layout.

Selection Notes

Select this component for systems requiring eight simultaneous channels with integrated front-end conditioning. The 40 MSPS speed grade offers a balance between performance and power consumption compared to the 50 MSPS variant. Consider the 100-lead TQFP package for standard surface-mount assembly processes.

Part Context

This part belongs to the AD9273 family of octal ultrasound ADCs from Analog Devices. It shares architectural similarities with the AD9272 but integrates additional front-end components. The -40 designation specifies the operational speed grade within the product line.

Replacement Considerations

The AD9273BBCZ-40 serves as a pin-compatible alternative utilizing a 144-ball BGA package instead of the TQFP form factor.
