AD9276BSVZ

Overview

The AD9276BSVZ is an octal analog-to-digital converter (ADC) integrating low noise preamplifiers (LNA), variable gain amplifiers (VGA), antialiasing filters (AAF), and continuous wave (CW) I/Q demodulators. It features eight independent channels with 12-bit resolution operating at sampling rates from 10 MSPS to 80 MSPS. The device utilizes a single 1.8 V supply for the ADC core and a 3.0 V supply for the analog front end, achieving low power consumption of 195 mW per channel in TGC mode and 94 mW per channel in CW Doppler mode.

Feature Summary

• Integrated signal chain: LNA, VGA, AAF, 12-bit ADC, and CW I/Q demodulator per channel
• Low input-referred noise: 0.75 nV/√Hz typical at 5 MHz with 21.3 dB LNA gain
• Programmable second-order antialiasing filter with LPF cutoff from 8 MHz to 18 MHz
• Serial LVDS digital outputs with data clock (DCO±) and frame clock (FCO±)

Applications

• Medical imaging and ultrasound systems
• Automotive radar applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or direct manufacturer channels. Confirm RoHS compliance status and check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure ordering suffix matches required temperature range and package variant specifications.

Selection Notes

Select based on required sampling rate modes: Mode I (40 MSPS), Mode II (65 MSPS), or Mode III (80 MSPS). Verify power supply compatibility with 1.8 V and 3.0 V rails. Consider thermal management requirements given the 100-lead TQFP_EP package and total power dissipation up to 2050 mW in TGC mode.

Part Context

The AD9276 belongs to a family of high-integration ultrasound receiver solutions. It consolidates multiple discrete components into a single 16 mm × 16 mm package, reducing board space and system complexity compared to traditional multi-chip architectures for medical and radar signal processing.
