The FXPQ3115BVT1 is a compact, piezoresistive, absolute pressure sensor with an I2C digital interface. FXPQ3115BVT1 has a wide operating range of 20 kPa to 110 kPa. 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 non-toxic, non-allergenic elastomer which meets all United States Pharmacopeia (USP) biological testing class VI requirements. The gel properties allow uniform pressure transmission to the MEMS diaphragm.
