Analog Devices Inc.'s AD9670 Octal Ultrasound Receiver
Analog Devices Inc. introduces the industryís first octal (eight-channel) ultrasound receiver with on-chip digital I/Q demodulation and decimation filtering. Because of the embedded demodulation and decimation feature, ADIís AD9670 is the first ultrasound receiver able to condition eight channels of data from RF to a baseband frequency, reducing the processing load on the system FPGA (field-programmable gate array) by at least 50 percent compared to other receivers. The AD9670 also integrates a low-noise amplifier, variable gain amplifier, anti-aliasing filter, and a 14-bit, A/D converter with the industryís highest sample rate (125 MSPS) and best SNR (signal-to-noise ratio) performance (75 dB) for enhanced ultrasound image quality. The new octal receiver is the latest addition to Analog Devicesí award-winning ultrasound receiver portfolio and is designed for mid- to high-end portable and cart-based ultrasound systems.
