LPS331AP Overview
Description
The LPS331AP is an ultra compact absolute piezoresistive pressure sensor. It includes a monolithic sensing element and an IC interface able to take the information from the sensing element and to pr.
Key Features
- It is capable to detecting pressure and is manufactured using a dedicated process developed by ST, called VENSENS
- The VENSENS process allows to build a monosilicon membrane above an air cavity with controlled gap and defined pressure
- The membrane is very small compared to the traditionally built silicon micromachined membranes
- Membrane breakage is prevented by an intrinsic mechanical stopper
- The package is holed to allow external pressure to reach the sensing element
