FXPS7550DS4ST1

FXPS7550DS4ST1 is a digital absolute pressure sensor. It is a high-performance, high-precision barometric absolute pressure (BAP) sensor consisting 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. Furthermore, the sensor employs an on-demand digital self-test for the digital IC and the MEMS transducers.
