Octal ultrasound transceiver from Maxim saves 40% space and 30% power

Maxim Integrated Products has released MAX2082, an octal ultrasound transceiver, which claimed by Maxim to save 40% board space and consumes 30% less power than conventional architecture in designing ultrasound medical equipment.

MAX2082 integrates 8 channels of 3-level 200V pulsers and T/R switches, an octal ADC, octal LNA, 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, which can be used clinics.

Maxim says "Traditional designs include over nine components in the T/R switch alone for each of the channels on a typical 128-channel system, 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 as per Maxim:
Higher image quality and performance: improved system sensitivity and image quality through an ultra-low noise figure (2.8dB at RIN = RS = 200Ω) and a high-dynamic-range receiver (76dBFS SNR at fIN = 5MHz and 2MHz bandwidth)
Space savings: high integration saves 40% more area than 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

"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:
Available in a 10mm x 26mm BGA package.
