Rev. 5 — 28 May 2020
Product data sheet
1 General description
The FXPQ3115BV is a compact, piezoresistive, absolute pressure sensor with an I2C digital interface. FXPQ3115BV 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 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.
