Integrated Octal Receivers Optimize Image Quality and Power Performance in Ultrasound Systems
The AD9272 offers the industry's lowest input-referred noise (0.75 nV/√Hz @ 5 MHz typical) when operating under real-world conditions and delivers 6 dB/√Hz better input dynamic range than competing devices. For portable ultrasound equipment, the AD9273 has industry-leading power dissipation of less than 109 mW per channel at 12 bits and 40 MSPS, extending portable ultrasound battery life.
Both the AD9272 and AD9273 feature a variable gain range of up to 42 dB, a selection of antialiasing filter options, and pin compatibility with other products in the ADI family. The AD9272 contains an ADC with a conversion rate of up to 80 MSPS, while the AD9273 includes an ADC with a conversion rate of up to 50 MSPS. Both the AD9272 and AD9273 provide medical equipment designers with the flexibility to scale power and performance for different imaging modes. The SPI feature allows designers to optimize an ultrasound signal processing architecture for any given imaging mode, probe, or power requirement. By simply changing SPI registers, designers will have the flexibility to achieve the best possible noise performance or longest battery life. An easy to use software tool offered by ADI simplifies implementation of each configuration. The AD9272 and AD9273 offer a crosspoint switch that was specifically designed to interface with the AD8339 quad programmable I/Q demodulator with phase shifter, which is ideally suited for CW Doppler ultrasound systems. The devices also complement ADI's AD8021 low noise high speed amplifiers; the AD7980 16-bit, 1 MSPS PulSAR® ADC; and the ADR433 5.0 V ultralow noise voltage reference. These offerings represent the broadest IC product portfolio specifically geared toward the medical imaging and ultrasound markets available today. Both the AD9272 and AD9273 come in a 100-lead TQFP (thin quad flat package) and operate over a temperature range of –40°C to +85°C.
