MAX2082CXD+

MAX2082CXD+ is world’s first fully-integrated octal ultrasound transceiver. This 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. The highly compact receiver with T/R switch, LNA, input coupling and feedback capacitors, variable gain amplifier (VGA), anti-aliasing filter (AAF), analogue-to-digital converter (ADC), and digital high pass filter (HPF) achieves an ultra-low noise figure with RS = RIN = 200 ohm 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. It is used in ultrasound imaging applications.
