MP4833A is a 32-channel, high-voltage, single-pole single-throw (SPST) analogue 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 32bit serial shift register, followed by a 32bit data latch. A data out pin (DOUT) allows multiple devices to be cascaded together. This helps minimize the number of input/output (I/O) control lines. A logic high signal in the data latch turns on the corresponding analogue switch, a logic low signal turns off the corresponding analogue switch. The MP4833A does not require any high voltage supplies. It only requires two low voltage supplies (3.3V and 10V). The analogue switch can block or pass analogue voltages up to ±90V with peak currents of up to ±2A. Applications includes medical ultrasound imaging and non-destructive testing (NDT).
