AD9279BBCZ

Overview

The AD9279BBCZ is an octal analog front-end integrated circuit designed for medical ultrasound and automotive radar applications. It integrates eight independent channels, each containing a low-noise preamplifier (LNA), variable gain amplifier (VGA), antialiasing filter (AAF), and a 12-bit pipeline analog-to-digital converter (ADC). The device supports sampling rates up to 80 MSPS with a signal-to-noise ratio of 70 dB. It also features CW I/Q demodulators with programmable phase rotation. Power supplies include AVDD1 at 1.8 V, AVDD2 at 3.0 V, and DRVDD at 1.8 V. The component is housed in a 144-ball CSP-BGA package measuring 10 mm × 10 mm.

Feature Summary

• Eight-channel architecture integrating LNA, VGA, AAF, ADC, and CW I/Q demodulator
• 12-bit resolution with SNR of 70 dB at sampling rates up to 80 MSPS
• Low power consumption: 60 mW per channel in CW mode and 141 mW per channel in TGC mode
• Flexible power-down modes with fast recovery from standby (<2 μs) and power-down (<1 ms)

Applications

• Medical ultrasound beamformers
• Automotive radar systems

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm availability through authorized distributors as supply status may vary. Ensure compliance with RoHS directives and moisture sensitivity levels prior to procurement.

Selection Notes

Select this component when a compact, multi-channel solution is required for high-performance signal acquisition. The integrated VGA and LNA simplify system design by reducing external component count. Consider the 10 mm × 10 mm package size for space-constrained designs. Evaluate power requirements based on TGC or CW Doppler operating modes.

Part Context

The AD9279 belongs to a family of specialized analog front-ends developed by Analog Devices. It is distinct from standard ADCs by its inclusion of RF front-end processing stages like LNAs and VGAs directly on the silicon die. This integration targets applications requiring high dynamic range and low noise in a small footprint.
