MAX2082

Low-Power, High-Performance Octal Ultrasound Transceiver with Integrated AFE, Pulser, T/R Switch, and CWD Beamformer

Industry's Only Ultrasound Transceiver Saves 40% Power and Increases Reliability by Replacing Thousands of Discrete Components


Description

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.

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 highpass 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.

Separate mixers for each channel are made available for optimal CWD sensitivity yielding an impressive 149dBc/Hz dynamic range per channel at 1kHz offset from the 1.25MHz carrier.

The MAX2082 octal ultrasound front-end is available in a small 10mm x 23mm CSBGA package and specified over a 0°C to +70°C temperature range.
