Digital Absolute Pressure Sensor (20 to 550 kPa)
FXPS7xxxDI4ST1 and FXPS7xxxDS4ST1 are the recommend devices for new designs as the FXPS7xxxDI4T1 and FXPS7xxxDS4T1 are discontinued.
The FXPS7xxxDx4 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.
The FXPS7xxxDx4 uses either a 3.3 V or 5.0 V power supply. Furthermore, the sensor employs an on-demand digital self-test for the digital IC and the MEMS transducers.
