MAX2082CXD+

Drivers, Receivers, Transceivers Overview

The MAX2082CXD+ is a fully integrated octal ultrasound transceiver designed for high-channel-count portable and cart-based systems. It features eight high-performance 3-level pulsers capable of generating pulses up to ±105V with programmable current from 0.5A to 2A. The receiver integrates a T/R switch, LNA, VGA, anti-aliasing filter, 12-bit ADC, and digital HPF, achieving an ultra-low noise figure of 2.8dB at RIN = RS = 200Ω. Each channel provides 76dBFS SNR at 5MHz with a 2MHz bandwidth and 149dBc/Hz dynamic range for CWD applications. The device operates within a 0°C to +70°C temperature range and is housed in a compact 10mm x 23mm CSBGA package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'CXD+' against the manufacturer's official ordering guide to confirm the commercial temperature range (0°C to +70°C) and RoHS compliance status. Ensure the required evaluation kit or documentation matches the exact part revision. Confirm that the 336-CSBGA footprint requirements align with your PCB design capabilities before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing high-channel-count ultrasound front-ends requiring significant space and power reduction compared to discrete solutions. Consider the integrated pulser current capability and low-power receiver characteristics if system constraints demand efficient power management without sacrificing imaging performance or dynamic range.
