NXP FXPS7115DS4T1

The FXPS7115D4 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. 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 40 kPa to 115 kPa and over a wide temperature range of - 40°C to 130°C. The sensor comes in an industry- leading 4 mm × 4 mm × 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, industrial, and consumer applications.
