MP4895A

96-Channel, High-Voltage Analog Switch with Output Bleed Resistors and 5V Bias

Description

The MP4895A is a 96-channel, high-voltage analog 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 96 switches are configured as 32 1:3 multiplexers and demultiplexers. The MP4895A has 32 switch inputs. Each switch input is connected to three switch outputs (SWOUTA, SWOUTB, and SWOUTC) for a total of 96 switch outputs. The MP4895A is controlled by a 96-bit serial shift registers, followed by a 96-bit data latches. The switches can be turned on/off via the 96-bit serial shift register.

The MP4895A does not require any high-voltage supplies. Only two low-voltage supplies are required (3.3V and 5V). The analog switch can block or pass analog voltages up to ±90V with peak currents of up to ±1.8A.

The MP4895A is available in a BGA-144 (10mmx10mm) package.

The MP4835A 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 transmission, and can 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 helps minimize the number of input/output (I/O) control lines. A logic high signal in the data latch turns the corresponding analog 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 5V). The analog switch can block or pass analog voltages up to ±100V with peak currents of up to ±1.8A. The MP4835A is available in a QFN-72 (10mmx10mm) package.
