The transceiver replaces thousands of discrete components in any ultrasound system and claims to save 40% board space and consume 30% 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, non-invasive 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.

The device 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% of the space required for conventional solutions and is especially beneficial for portable systems. Traditional designs include more than 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.

The MAX2082 octal ultrasound transceiver offers 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 MHz and 2MHz bandwidth).

The transceiver combines five separate blocks into one IC to replace thousands of discrete components in a standard system.

“The shift to more portable ultrasound equipment plays to Maxim’s strengths of integration and low power. Maxim is the only supplier that combines the high- and low-voltage blocks into one package,” said Manav Malhotra, Executive Business Manager at Maxim Integrated.

Availability and Pricing

The MAX2082 is available in a 10 mm x 26 mm BGA package and is specified across the 0 °C to +70 °C temperature range. Pricing starts at $60.00 (1000-up).
