Part Number Status
MAX2082 Active: In Production.


The MAX2082 is the industry's first fully integrated octal ultrasound transceiver. The device is optimized for high channel count, high-performance portable and cart-based ultrasound systems. The easy-to-use transceiver allows the user to achieve "high end" 2D and Doppler imaging capability using substantially less space and power.

The transceiver transmitters are high-performance 3-level 2A pulsers capable of generating high voltage pulses up to ±105V. All eight channels have overvoltage-embedded protection diodes and integrated active return-to-zero clamps. The transmitters also feature embedded floating power supplies (FPSs) to eliminate the need for bulky external pulser driver coupling capacitors. The highly compact receiver with T/R switch; LNA; input coupling and feedback caps; and VGA, AAF, ADC, and digital HPF achieves an ultra-low 2.8dB noise figure at RS = RIN = 200Ω at a very low 135mW per channel power dissipation at 50Msps. The receive channel has been optimized for second harmonic imaging with -70dBFS second harmonic distortion performance at fIN = 5MHz over the full TGC range. Dynamic range has also been optimized for exceptional pulsed and color flow Doppler performance under high-clutter conditions. The full receive channel exhibits an exceptional 75.7dBFS SNR at 5MHz with a 2MHz bandwidth. The bipolar front-end and CMOS ADC have also been optimized for an exceptionally low near-carrier modulation noise of 137dBc/Hz at 1kHz offset from a 5MHz tone for excellent low-velocity Doppler sensitivity.

The MAX2082 also includes an octal CWD beamformer for a full Doppler solution. Separate mixers for each channel are made available for optimal CWD sensitivity yielding an impressive 151dBc/Hz dynamic range per channel at 1kHz offset from a 1.25MHz carrier.

The MAX2082 octal ultrasound front-end is available in a small 10mm x 26mm BGA package and specified over the 0°C to +70°C temperature range.
