%#"% % $%%'$ ## & "!% motorola has developed a low cost, high volume, miniature pressure sensor package which is ideal as a submodule 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 patented, piezoresistive implant technology, along with the added feature of onchip, thinfilm temperature compensation and calibration. features: ? low cost ? patented piezoresistive strain gauge implant, temperature compensation and calibration all integrated on a single, monolithic sensor die. ? pressure range available: 0300 mmhg ? polysulfone (mindell s1000) case material (medical, class vi approved) motorola is offering the chip pak option package. applicationspecific parts will have an aspxo prefix, followed by a four digit number, unique to the specific customer. devices will be shipped in a tape and reel packaging. 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. maximum ratings rating symbol value unit overpressure (backside) p max 125 psi burst pressure p burst 1000 kpa supply voltage v smax 10 vdc storage temperature t stg 25 to + 85 c operating temperature t a + 15 to + 40 c motorola's MPX2300DT1 pressure sensors. motorola's MPX2300DT1 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. a silicone dielectric gel that has been used extensively in implants covers the silicon piezoresistive sensing element. the gel is a nontoxic, nonallergenic polymer system which passes pyrogen testing, as well as meeting all usp xx bio- logical testing class vi requirements. the properties of the gel allow it to transmit pressure uniformly 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 transducers. a biomedically ap- proved opaque filler in the gel prevents bright operating room lights from affecting the performance of the sensor. senseon and xducer are trademarks of motorola, inc. order this document by MPX2300DT1/d
