1 / 4 page MPXC2011DT1 MPXC2012DT1 1 Sensor Device Data Freescale Semiconductor High Volume Sensor for Low Pressure Applications Freescale Semiconductor 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 Freescale Semiconductor’s unique sensor die with its piezoresistive technology, along with the added feature of on--chip, thin--film temperature compensation and calibration. NOTE: Freescale Semiconductor 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. Freescale Semiconductor ’s MPXC2011DT1/ MPXC2012DT1 Pressure Sensor has been designed for medical usage by combining the performance of Freescale Semiconductor’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 Freescale Semiconductor recommended choices for future use and best overall value.
