MP4816A
16-Channel High Voltage Analog Switch
With Output Bleed Resistors
The Future of Analog IC Technology
PRELIMINARY SPECIFICATIONS SUBJECT TO CHANGE
DESCRIPTION
FEATURES
The MP4816A is a 16-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
16 Channels
Up to ±90V Analog Signals
12.5 Ω Typical Switch Resistance
±2.0A Typical Switch Peak Current
Off-Isolation of -60dB at 5.0MHz
Integrated Output Bleed Resistor
80MHz Clock Frequency
The output switches are controlled by a 16-bit
serial shift register followed by a 16-bit data
latch. A data out, Dout, pin is provided to allow
for multiple devices to be cascaded together.
This will help minimize the number of
input/output, I/O, control lines. A logic High in
the data latch will turn on the corresponding
analog switch whereas a logic Low will turn it
off.
APPLICATIONS
Medical Ultrasound Imaging
NDT, Non-Destructive Testing

The MP4816A does not require any high
voltage supplies. Only two low voltage supplies
are required, 3.3V and 10V. The analog switch
can block or pass analog voltages up to ±90V
with peak currents of up to ±2.0A.
