FXPS7550D4 Digital absolute pressure sensor, 20 to 550 kPa Rev. 5 — 15 July 2019 Product data sheet 1 General description The FXPS7550D4 high-performance, high-precision barometric absolute pressure (BAP) sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated digital output. The sensor is based on NXP's high-precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. This sensor delivers highly accurate pressure and temperature readings through either a serial peripheral interface (SPI) or an inter-integrated circuit (I2C) interface. The FXPS7550D4 uses either a 3.3 V or 5.0 V power supply.
