LPS225HBTR Datasheet PDF - ST Microelectronics

●The LPS225HB is an ultra-compact piezoresistive absolute pressure sensor. It includes a monolithic sensing element and an IC interface which communicates a digital signal from the sensing element to the application.

●The sensing element, which detects absolute pressure, consists of a suspended membrane inside a single mono-silicon substrate and is manufactured using 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 characteristics of the sensing element.

●The LPS225HB is available in a full-mold, holed LGA package (HLGA). It is guaranteed to operate over a temperature range extending from -40 °C to +85 °C. The package is holed to allow external pressure to reach the sensing element.
