The MP4833A is a 32-channel, high-voltage, single-pole single-throw (SPST) analog switch with integrated output bleed resistors. It is designed to multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZT), and is ideal for medical ultrasound imaging applications.

The output switches are controlled by a 32-bit serial shift register, followed by a 32-bit data latch. A data output pin (DOUT) allows multiple devices to be cascaded together. This minimizes the number of input/output (I/O) control lines. A logic high signal in the data latch turns on the corresponding analog switch; a logic low signal turns off the corresponding analog switch.

The MP4833A does not require any high-voltage supplies. It only requires two low-voltage supplies (3.3V and 10V). The analog switch can block or pass analog voltages up to ±90V with peak currents of up to ±2A.

The MP4833A is available in a BGA-80 (7mmx7mm) package.
