FXPS7250A4ST1

FXPS7250A4ST1 is an analogue absolute pressure sensor. It is a high-performance, high-precision absolute pressure sensor consisting of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated analogue output. This sensor is ideal for many automotive applications such as manifold air pressure (MAP), comfort seating, and other applications requiring operating absolute pressure ranges up to 250kPa. The sensing element is based on NXP's high-precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. It delivers highly accurate radiometric analogue readings of absolute pressure while operating from either a 3.3V or 5.0V power supply.
