MP4835AGRD-T

MP4835A is a 32-channel, high-voltage, single-pole/single-throw (SPST) analogue switch with integrated output bleed resistors, designed for medical ultrasound imaging applications. It is designed to multiplex the transmission and can receive voltages to and from multiple piezoelectric transducers (PZTs). The output switches are controlled by a 32bit serial shift register, followed by a 32bit data latch. A data out (DOUT) pin is provided to allow for 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 the corresponding analogue switch on, whereas a logic low signal turns it off. The MP4835A does not require any high-voltage supplies. Only two low-voltage supplies are required (3.3V and 5.0V). The analogue switch can block or pass analogue voltages up to ±100V with peak currents of up to ±1.8A. Applications include medical ultrasound imaging and non-destructive testing (NDT).
