Description
The MP4832A is a 32-channel high voltage single-pole single-throw, SPST, analog switch with integrated output bleed resistors designed for medical ultrasound imaging applications. It is designed to multiplex the transmit and receive voltages to and from multiple piezoelectric transducers, PZTs. The output switches are controlled by a 32-bit serial shift register followed by a 32-bit data latch. A data out, Dout, pin is provided to allow for multiple devices to be cascaded together. This will help minimize the number of input/output, I/O, control lines. A logic High in the data latch will turn on the corresponding analog switch whereas a logic Low will turn it off. The MP4832A does not require any high voltage supplies. Only two low voltage supplies are required, 3.3V and 10V. The analog switch can block or pass analog voltages up to ±90V with peak currents of up to ±2.0A. The MP4832A is available in QFN 72-pin 10mm x 10mm package.

APPLICATION
ULTRASOUND MACHINES (PORTABLE)APPLICATIONMedical ultrasound imaging uses high-frequency sound waves to view internal structures inside the body, such as internal organs, blood vessels, and developing fetuses in the womb. Ultrasound technology is in high demand as it is a less invasive, less expensive diagnostic method than imaging techniques such as MRIs or CT scans. Advances in integrated technology have allowed the introduction of port...

ARTICLE
HIGH-VOLTAGE ANALOG SWITCHES FOR MEDICAL ULTRASOUNDARTICLEMedical ultrasound imaging is a non-invasive method of viewing internal organs and structures of the human body using high-frequency acoustic waves. By sending an acoustic wave into the human body and listening to the acoustic echoes, an ultrasound image can be created. Given the acoustic properties of the human body, the optimum frequency range for general medical ultrasound imaging is 1.0MHz to ...
