MP4865A

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

Datasheet

Description

The MP4865A is a 64-channel, high-voltage, single-pole single-throw (SPST) analog switch with integrated output bleed resistors. The device can multiplex the transmit and receive voltages to and from multiple piezoelectric transducers (PZTs), and is designed for medical ultrasound imaging applications.

The output switches are controlled by a 64-bit serial shift register, followed by a 64-bit data latch. The data out pin (DOUT) allows for multiple devices to be cascaded together. This helps to minimize the number of input/output (I/O) control lines. When the data latch is logic high, the corresponding analog switch turns on; when the data latch is low, the corresponding switch turns off.

The MP4865A does not require any high-voltage supplies. It only requires two low-voltage supplies (3.3V and 5V). The analog switch can block or pass analog voltages up to ±90V with peak currents up to ±1.8A.

The MP4865A is available in a BGA-144 (10mmx10mm) package.

The EV4865A-BD-00A is an evaluation board designed to demonstrate the capabilities of the MP4865A, a high-voltage, 64-channel analog switch. The MP4865A is designed for medical ultrasound applications. It can also be used for non-destructive tests (NDTs), as the application is very similar to medical ultrasound applications.

The high-voltage analog switches are used to multiplex the transmitter and receiver circuitries to different piezoelectric transducer (PZT) elements. The MP4865A has a resistor that is connected between ground and the output pins (SWOUTx). This ensures that a significant DC voltage does not build up across the PZT element. The switches can be turned on/off via a serial 64-bit shift register. The serial control interface minimizes the number of input/output (I/O) connections.
