MEMS pressure sensor: 260-1260 hPa absolute digital output barometer

The LPS25HB is a piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which communicates through I2C or SPI from the sensing element to the application.

The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST.

The LPS25HB is available in a full-mold, holed LGA package (HLGA). It is guaranteed to operate over a temperature range extending from -30 to +105 °C. The package is holed to allow external pressure to reach the sensing element.
