FXPQ3115BVST1 is a I²C precision pressure sensor with altimetry. It is a compact, piezoresistive, absolute pressure sensor with an I²C digital interface. It has a wide operating range of 20kPa to 110kPa. This sensor is ideal for inhalers, continuous positive airway pressure (CPAP) masks, or other medical devices coming in contact with a patient's airway. The MEMS and ASIC die are coated with a biomedically approved gel. The gel is a nontoxic, nonallergenic elastomer which meets all United States Pharmacopeia (USP) biological testing class VI requirements. The gel properties allow uniform pressure transmission to the MEMS diaphragm. A high-resolution ADC provides fully compensated and digitized outputs for pressure in Pascals and temperature in °C. Application includes inhalers/nebulizers, medical tablets, health activity monitors, oxygen concentrators, CPAP machine and mask, spyrometry.
