AD9272BSVZRL-80

Overview

The AD9272BSVZRL-80 is an octal analog front-end integrated circuit manufactured by Analog Devices Inc. It integrates eight independent channels, each containing a low noise preamplifier (LNA), a variable gain amplifier (VGA), an antialiasing filter (AAF), and a 12-bit analog-to-digital converter (ADC). The device supports sampling rates up to 80 MSPS with a typical signal-to-noise ratio of 70 dB and spurious-free dynamic range of 75 dB. It features a serial LVDS interface for data output and includes an 8x8 differential crosspoint switch for continuous wave Doppler applications. The component operates within the industrial temperature range of -40°C to +85°C.

Feature Summary

• Eight-channel architecture integrating LNA, VGA, AAF, and 12-bit ADC per channel
• Sampling rate up to 80 MSPS with SNR of 70 dB and SFDR of 75 dB
• Integrated 8x8 differential crosspoint switch supporting CW Doppler mode
• Programmable second-order antialiasing low-pass filter from 8 MHz to 18 MHz

Applications

• Medical imaging and ultrasound systems
• Automotive radar systems

Procurement Notes

Verify that the ordering suffix RL indicates tape and reel packaging when sourcing components. Confirm the speed grade corresponds to the -80 designation for 80 MSPS operation. Ensure compatibility with the required power supply voltages: AVDD1 at 1.8 V, AVDD2 at 3.0 V, and DRVDD at 1.8 V. Check for RoHS compliance status in current distributor listings.

Selection Notes

Select the AD9272BSVZRL-80 when system requirements demand high-speed sampling up to 80 MSPS with integrated signal conditioning. This model provides lower power consumption compared to lower speed grades during continuous wave Doppler operations. Verify that the 100-lead TQFP package fits the available PCB real estate constraints.

Part Context

This component belongs to the AD9272 family of octal ultrasound ADCs. Other variants include the AD9272BSVZ-40 and AD9272BSVZ-65, which offer maximum sampling rates of 40 MSPS and 65 MSPS respectively. All models share identical pinouts and functional blocks but differ in performance specifications related to clock frequency and power dissipation.

Replacement Considerations

Direct replacements within the same package and functionality are the AD9272BSVZ-40 and AD9272BSVZ-65. These parts maintain electrical compatibility but operate at lower maximum sampling frequencies.
