2 / 2 page absolute digital output barometer 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 provide a digital signal to the external world. The sensing element consists of a suspended membrane inside a single mono- silicon substrate. It is capable of detecting pressure and is manufactured using a specific proprietary process called VENSENS. The VENSENS process allows a mono- silicon membrane to be produced above an air cavity with controlled gap and defined pressure. The membrane is very small compared to traditional silicon micromachined membranes. Membrane breakage is prevented by intrinsic mechanical stoppers. The IC interface is manufactured using a standard CMOS process. This allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The LPS331AP is available in a small plastic land grid array (HCLGA) package and is guaranteed to operate over an extended temperature range from -40 to +85 °C. The package is holed to allow external pressure to reach the sensing element. evaluation Kit ST’s pressure sensors are supported by an evaluation kit that consists of a motherboard (STEVAL-MKI109V2) and a plug-in module that includes the LPS331AP sensor (STEVAL- MKI120V1). Once the adapter is plugged in, the board can be connected to a host PC via USB so the device’s capabilities can be easily evaluated via an intuitive graphic user interface.
