MP4864A

64-Channel, High-Voltage, SPST

Analog Switch with Output Bleed Resistors

DESCRIPTION

FEATURES

The MP4864A is a 64-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 transmit and receive

voltages to and from multiple piezoelectric

transducers (PZTs).

 No High-Voltage Supplies Required

 64 Channels

 Up to ±90V Analog Signals

 14Ω Typical Switch Resistance

 ±2.0A Typical Switch Peak Current

 Off-Isolation of -66dB at 5MHz

 Integrated Output Bleed Resistors

 80MHz Clock Frequency

The output switches are controlled by a 64-bit

serial shift register, followed by a 64-bit data

latch. A data out (DOUT) pin 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 analog switch; a logic low

signal turns off the corresponding analog switch.

 Available in a BGA-144 (10mmx10mm)

Package

APPLICATIONS

 Medical Ultrasound Imaging

 Non-Destructive Testing (NDT)

All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.

For MPS green status, please visit the MPS website under Quality

Assurance. “MPS”, the MPS logo, and “Simple, Easy Solutions” are

The MP4864A does not require any high-voltage

supplies. It only requires two low-voltage

supplies (3.3V and 12V). The analog switch can

block or pass analog voltages up to ±90V with

peak currents of up to ±2A. The MP4864A is

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