LM96530 Overview
The LM96530 is an eight-channel monolithic highvoltage, 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 plete medical ultrasound solution targeted towards low-power, portable systems. The LM96530 contains eight high-voltage T/R switches with integrated clamping diodes.
