The MAX2082 octal ultrasound transceiver combines five separate blocks into one IC, ultimately replacing thousands of discrete components in an ultrasound system. It saves 40 % board space and consumes 30 % less power than the conventional discrete architecture.
Maxim Integrated’s IC integrates eight channels of three-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 BGA package that measures less than 10 square inches. Traditional designs include over nine components in the T/R switch alone for each of up to 128 channels.
Improved system sensitivity and image quality through an ultra-low noise figure (2.8 dB at RIN = RS = 200 Ω) and a high-dynamic-range receiver (76 dBFS SNR at fIN = 5 MHz and 2-MHz bandwidth) result in higher image quality and performance. Image quality also gets a boost thanks to minimized power-supply noise and switching noise.
The MAX2082 is specified over the 0 to +70°C temperature range.
