FXPS7250DI4ST1 Digital absolute pressure sensor, 20 kPa to 250 kPa

The ​​​FXPS7250xD4S 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 ST'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.

The sensor operates over a pressure range of 20 kPa to 250 kPa and over a wide temperature range of −40 ºC to 130 ºC.

The sensor comes in an industry-leading 4 mm x 4 mm x 1.98 mm, restriction of hazardous substances (RoHS) compliant, high power quad flat no lead (HQFN) package suitable for small PCB integration. Its AEC-Q100 compliance, high accuracy, reliable performance, and high media resistivity make it ideal for use in automotive and industrial applications.
