The LM96530 is an eight-channel monolithic high-voltage, high-speed T/R (Transmit/Receive) switch for multi-channel medical ultrasound applications. It is well-suited for use with Texas Instrument’s LM965XX series chipset which offers a complete medical ultrasound solution targeted towards low-power, portable systems.
The LM96530 contains eight high-voltage T/R switches with integrated clamping diodes. This chip protects the inputs of the receive channel's LNA (Low Noise Amplifier) from the high-voltage pulses of the transmit channel. Advanced features include a diode bridge with internal current sources that are programmable via an external resistor. Low-power operation is enabled via per-channel-selectable switching.
Texas Instruments also offers a development package for sale which includes a driver hardware and software package with a graphical user interface for configuration and monitoring.
