STMicroelectronics FXPS7550A4S
The FXPS7550A4S high-performance, high-precision absolute pressure sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated analog output. This sensor is ideal for many automotive applications such as manifold air pressure (MAP), turbo MAP, comfort seating, and other applications requiring operating absolute pressure ranges up to 550 kPa. The sensing element is based on ST's high precision capacitive pressure cell technology.| Part No. | FXPS7550A4S |

DESCRIPTION
The architecture benefits from redundant pressure transducers as an expanded quality measure. It delivers highly accurate ratiometric analog readings of absolute pressure while operating from either a 3.3 V or 5.0 V power supply. The sensor operates over a pressure range of 20 kPa to 550 kPa and over a wide temperature range of –40 ºC to 130 ºC.
