FXPS7250DI4ST1

FXPS7250DI4ST1 is a digital absolute pressure sensor. It is a high-performance, high-precision barometric absolute pressure sensor consisting of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital IC producing a fully calibrated digital output. It 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 or an inter-integrated circuit (I²C) interface. The application includes engine management digital MAP and BAP, comfort seating, small engine control, liquid propane gas or compressed natural gas engine management (automotive), compressed air, manufacturing line control, gas metering, weather stations (industrial), blood pressure monitor, medicine dispensing systems, white goods (medical/consumer).
