LM96530SQX/NOPB

Specialized Overview

The LM96530SQX/NOPB is an eight-channel monolithic high-voltage transmit/receive switch designed for multi-channel medical ultrasound applications. It features integrated clamping diodes that limit output voltage to ±0.7V, protecting low-noise amplifier inputs from high-voltage pulses up to ±60V. The device supports transducer frequencies from 1MHz to 20MHz and accepts continuous-wave signals within the specified input range. Key electrical parameters include a typical on-resistance of 18Ω, off-isolation of -58dB at 5MHz, and channel crosstalk of -73dB at 5MHz. It operates with dual 5V analog supplies and a 2.5V to 3.3V logic supply.

Specialized Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm package integrity and pin alignment prior to installation. Ensure proper handling procedures are followed due to electrostatic sensitivity. Review the latest product availability status as the device may be subject to lifecycle changes.

Specialized Selection Notes

Select this component for designs requiring high-voltage isolation and low-distortion switching in ultrasound arrays. Verify that the external bias resistor meets the required current source scaling between 0 and 8mA. Ensure the system power sequencing keeps the negative substrate bias as the most negative supply during operation.

Specialized Part Context

This part belongs to the LM965XX chipset series from Texas Instruments, which provides a complete solution for portable, low-power ultrasound systems. It is specifically engineered to interface with companion pulser and beamformer components, enabling scalable multi-channel architectures.
