AD9273BSVZ-50

Overview

The AD9273BSVZ-50 is an octal analog-to-digital converter (ADC) integrating low noise preamplifiers (LNA), variable gain amplifiers (VGA), antialiasing filters (AAF), and a 12-bit ADC core. It operates at sampling rates up to 50 MSPS with a typical Signal-to-Noise Ratio (SNR) of 63.5 dBFS at -10 dBFS input. The device features single-ended inputs with maximum voltage ranges of 733 mV p-p, 550 mV p-p, or 367 mV p-p depending on LNA gain settings. Power consumption is 109 mW per channel in Time Gain Control (TGC) mode at 40 MSPS. It utilizes LVDS serial outputs and includes an 8x8 differential crosspoint switch for CW Doppler applications.

Feature Summary

• Eight integrated channels combining LNA, VGA, AAF, and 12-bit ADC
• Programmable second-order antialiasing filter (LPF: 8 MHz to 18 MHz)
• Integrated 8x8 differential crosspoint switch for CW Doppler mode
• LVDS serial output with data clock (DCO±) and frame clock (FCO±)

Applications

• Medical imaging and ultrasound systems
• Automotive radar applications

Procurement Notes

Verify the specific suffix 'SVZ' corresponds to the TQFP-EP-100 package and industrial temperature range (-40°C to +85°C). Confirm that the '-50' designation indicates the 50 MSPS speed grade. Ensure compliance with RoHS standards as specified in the manufacturer documentation.

Selection Notes

Select this component when eight independent signal paths are required within a compact footprint. The integrated LNA and VGA simplify front-end design by eliminating external discrete components. Verify that the system clock supports LVPECL, CMOS, or LVDS logic levels for optimal performance.

Part Context

This part belongs to the AD9273 family of octal ADCs. The AD9273BSVZ-50 specifically denotes the B-grade silicon, SVZ TQFP package, and 50 MSPS speed bin. Other variants include the AD9273-25 and AD9273-40 for lower sampling rates, and a BGA package option.

Replacement Considerations

Direct pin-compatible replacements within the same family include the AD9273BSVZ-25 and AD9273BSVZ-40, which offer lower maximum sampling rates but share identical pinouts and functionality.
