Ultrasound designers can now reduce form factor and improve image quality and reliability with the MAX2082 octal ultrasound transceiver from Maxim Integrated (Munich, Germany). This highly integrated transceiver replaces thousands of discrete components in any ultrasound system. It saves 40 percent board space and consumes 30 percent less power than the conventional architecture.

Ultrasound equipment is quickly moving from the typical hospital room to smaller clinics, doctor’s offices, and patient’s homes as a low cost, noninvasive diagnostic tool. Meanwhile, customers are demanding higher levels of performance and more affordable solutions. Ultrasound systems must now shrink in size and provide more clarity in images, so testing and diagnoses become more convenient, more immediate, and more accurate. The solution is the MAX2082, a complete, low-power ultrasound transceiver solution. It integrates 8 channels of 3-level 200 V pulsers and T/R switches, an octal ADC, octal LNA, and octal VGA, CW mixers, anti-aliasing filters, and coupling capacitors into a small package requiring less than 10 square inches. This is 40 percent of the space required for conventional solutions and is especially beneficial for portable systems. Traditional designs include over nine components in the T/R switch alone for each of up to 128 channels, so the MAX2082 displaces thousands of discrete parts. Power-supply noise and switching noise are all minimized in the MAX2082 for superior image quality.

Key Advantages

  • Higher image quality and performance: improved system sensitivity and image quality through an ultra-low noise figure (2.8 dB at RIN = RS = 200Ω) and a high-dynamic-range receiver (76 dBFS SNR at fIN = 5 and 2 MHz bandwidth).
  • Space savings: high integration saves 40 % more area than a conventional architecture.
  • Higher integration and reliability: combines five separate blocks into one IC, replacing thousands of discrete components in a standard system.
  •  Lower power: consumes 30 % less power than conventional architecture.
