AD9272BSVZRL-65

Overview

The AD9272BSVZRL-65 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 with sampling rates up to 80 MSPS. Key electrical parameters include a signal-to-noise ratio (SNR) of 70 dB, spurious-free dynamic range (SFDR) of 75 dB, and input-referred noise voltage of 0.75 nV/√Hz at 21.3 dB LNA gain. The device operates on 1.8 V and 3.0 V supplies, dissipating 195 mW per channel at 40 MSPS. It utilizes serial LVDS outputs and includes an 8 × 8 crosspoint switch for continuous wave Doppler applications.

Feature Summary

• Octal architecture integrating LNA, VGA, AAF, and 12-bit ADC in a single 100-lead TQFP package
• Programmable second-order antialiasing filter with cutoff frequencies ranging from 8 MHz to 18 MHz
• Integrated 8 × 8 differential crosspoint switch supporting continuous wave Doppler mode
• Serial LVDS data interface with dedicated data clock (DCO±) and frame clock (FCO±) outputs

Applications

• Medical imaging and ultrasound systems
• Automotive radar applications

Procurement Notes

Verify the specific speed grade suffix (-65) against the manufacturer's current ordering guide to confirm availability and exact performance specifications relative to the -40 and -80 variants. Confirm RoHS compliance status and packaging details directly with Analog Devices or authorized distributors prior to procurement.

Selection Notes

Select the AD9272BSVZRL-65 when system requirements demand an 8-channel solution with integrated signal conditioning in a compact footprint. Ensure the 80 MSPS maximum sampling rate aligns with the application bandwidth needs. Verify power supply constraints match the required 1.8 V and 3.0 V rails and consider thermal management for the 100-lead TQFP package.

Part Context

The AD9272BSVZRL-65 belongs to the AD9272 family of octal ultrasound ADCs. The 'RL' suffix indicates reel packaging, while '-65' designates the specific speed grade variant optimized for operation up to 80 MSPS. This component consolidates multiple discrete signal chain stages into one integrated circuit to reduce board space and system complexity.

Replacement Considerations

Direct replacements within the same family include the AD9272BSVZ-40 and AD9272BSVZ-80, which share identical pinouts and functionality but differ in maximum sampling speed specifications.
