LPS25H

STMICROELECTRONICS  LPS25H  压力传感器, 绝对, 26 kPa, 126 kPa, 1.7 V, 3.6 V

The is an ultra compact absolute piezoresistive Pressure Sensor, includes a monolithic sensing element and an IC interface able to take the information from the sensing element and to provide a digital signal to the external world. The sensing element consists of a suspended membrane realized inside a single mono-silicon substrate. It is capable to detect pressure and is manufactured using a dedicated process developed by ST. The membrane is very small compared to the traditionally built silicon micro-machined membranes. Membrane breakage is prevented by an intrinsic mechanical stopper. The IC interface is manufactured using a standard CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The package is holed to allow external pressure to reach the sensing element.
