FXPS7115DI4ST1

FXPS7115DI4ST1 is a high-performance, high-precision barometric digital 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 I²C interface. Furthermore, the sensor employs an on-demand digital self-test for the digital IC and the MEMS transducers. The application includes engine management digital MAP and BAP, small engine control (automotive), compressed air, manufacturing line control, gas metering, weather stations (industrial), blood pressure monitor, medicine dispensing systems, and white goods (medical/consumer).
