DESCRIPTION

The MP4832 is a 32-channel high voltage single-

pole

single-throw,

SPST,

analog

switch

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 MP4832 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 ±100V with

peak currents of up to ±2.0A. The MP4832 is

available in a QFN 72-pin 10mm x 10mm

package.
