Analog Devices / Maxim Integrated MAX2082 Octal Ultrasound Transceiver

Analog Devices Inc. MAX2082 Octal Ultrasound Transceiver 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. 

The highly compact receiver with T/R switch, LNA, input coupling and feedback capacitors, variable gain amplifier (VGA), anti-aliasing filter (AAF), analog-to-digital converter (ADC), and digital high pass filter (HPF) achieves an ultra-low noise figure with RS = RIN = 200Ω at a very low 131mW per channel power dissipation at 50Msps. The receive channel has been optimized for second harmonic imaging with -66dBFS second harmonic distortion performance at fRF = 5MHz over the full gain range. The full receive channel exhibits an exceptional 76dBFS SNR at 5MHz with a 2MHz bandwidth.

Features

  • Minimizes PCB area and design cost
  • 8 Full channels of HV pulser, T/R-switch, LNA input and feedback coupling caps, LNA, VGA, AAF, CWD mixers, 12-Bit ADC, and digital HPF in a small 10mm x 23mm CSBGA package
  • Integrated HV pulser for simpler system design
  • High voltage 3 level pulsers (up to ±105V) with active return to zero and internal power-supply drivers for reduced external components
  • Programmable pulser current capability from 0.5A to 2A for reduced power consumption in lower voltage transmit modes like CWD
  • Extremely low propagation delay pulsers (18ns) with excellent rise and fall matching for excellent THD2 performance (-43dBc at 5MHz)
  • Integrated high-performance receiver improves system sensitivity
  • Ultra-low full-channel receiver noise figure of 2.8dB at RIN = RS = 200Ω (without T/R switch)
  • High dynamic range receiver with 76dBFS SNR at fIN = 5MHz and 2MHz bandwidth
  • Ultra-low power receiver (131mW per channel)
