Description

The LPS25H 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 realized inside a single mono-silicon

substrate. It is capable to detect the absolute

pressure and is manufactured with a dedicated

process developed by ST.

The membrane is very small compared to the

traditionally built silicon micromachined

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 LPS25H is available in a cavity holed LGA

package (HCLGA). It is guaranteed to operate

over a temperature range extending from -30 °C

to +105 °C. The package is holed to allow

external pressure to reach the sensing element.
