AD9675KBCZ

Overview

The AD9675KBCZ is an octal ultrasound analog front end (AFE) from Analog Devices Inc., designed for medical imaging and nondestructive testing. It integrates eight independent channels, each containing a low noise preamplifier (LNA), variable gain amplifier (VGA), antialiasing filter (AAF), 14-bit ADC, and digital RF decimator. The device supports sampling rates up to 125 MSPS with a typical SNR of 75 dB. It features a CW Doppler mode with harmonic rejection I/Q demodulator and programmable phase rotation. Digital outputs are provided via JESD204B Subclass 0 coded serial interfaces. The component operates within a temperature range of 0°C to 85°C and is housed in a 10 mm × 10 mm, 144-ball CSP_BGA package.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the required supply voltages (AVDD1 at 1.8 V, AVDD2 at 3.0 V, DVDD at 1.4 V, DRVDD at 1.8 V) match the system design. Ensure compatibility with the JESD204B interface requirements for lane configuration and clocking.

Selection Notes

Select this component when designing systems requiring high channel count integration for ultrasound applications. Evaluate power consumption based on the operating mode; TGC mode consumes approximately 150 mW per channel at 40 MSPS, while CW mode consumes 62.5 mW per channel. Consider the 144-ball CSP_BGA package constraints for PCB layout and thermal management during the design phase.

Part Context

This part belongs to the AD9675 series of ultrasound analog front ends. It is specifically engineered to provide a low-cost, low-power, and small-size solution for medical ultrasound systems. The device consolidates multiple signal chain components into a single chip to reduce system complexity and board space.

Replacement Considerations

Consult the manufacturer's datasheet for officially listed alternative part numbers or updated revisions within the same product family before considering substitution.
