High Volume Sensor for

Low Pressure Applications

Motorola has developed a low cost, high volume, miniature pressure sensor package

which is ideal as a sub–module component or a disposable unit. The unique concept of

the Chip Pak allows great flexibility in system design while allowing an economic solution

for the designer. This new chip carrier package uses Motorola’s unique sensor die with its

piezoresistive technology, along with the added feature of on–chip, thin–film temperature

compensation and calibration.

NOTE: Motorola is also offering the Chip Pak package in application–specific

configurations, which will have an “SPX” prefix, followed by a four–digit number, unique

to the specific customer.

Features:

• Low Cost

• Integrated Temperature Compensation and Calibration

• Ratiometric to Supply Voltage

• Polysulfone Case Material (Medical, Class V Approved)

• Provided in Easy–to–Use Tape and Reel

Application Examples

• Respiratory Diagnostics

• Air Movement Control

• Controllers

• Pressure Switching

NOTE: The die and wire bonds are exposed on the front side of the Chip Pak

(pressure is applied to the backside of the device). Front side die and wire protection

must be provided in the customer’s housing. Use caution when handling the devices

during all processes.

Motorola’s MPXC2011DT1/MPXC2012DT1 Pressure

Sensor has been designed for medical usage by combining

the performance of Motorola’s shear stress pressure sensor

design and the use of biomedically approved materials.

Materials with a proven history in medical situations have

been chosen to provide a sensor that can be used with

confidence in applications, such as invasive blood pressure

monitoring. It can be sterilized using ethylene oxide. The

portions of the pressure sensor that are required to be

biomedically approved are the rigid housing and the gel

coating.

The rigid housing is molded from a white, medical grade

polysulfone that has passed extensive biological testing

including: tissue culture test, rabbit implant, hemolysis,

intracutaneous test in rabbits, and system toxicity, USP.

The MPXC2011DT1 contains a silicone dielectric gel

which covers the silicon piezoresistive sensing element. The

gel is a nontoxic, nonallergenic elastomer system which

meets all USP XX Biological Testing Class V requirements.

The properties of the gel allow it to transmit pressure uni-

formly to the diaphragm surface, while isolating the internal

electrical connections from the corrosive effects of fluids,

such as saline solution. The gel provides electrical isolation

sufficient to withstand defibrillation testing, as specified in the

proposed Association for the Advancement of Medical

Instrumentation (AAMI) Standard for blood pressure trans-

ducers. A biomedically approved opaque filler in the gel pre-

vents bright operating room lights from affecting the

performance of the sensor.

The MPXC2012DT1 is a no–gel option.

Preferred devices are Motorola recommended choices for future use and best overall value.
