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. HLGA 10L (2.5 x 2.5 x 0.76 mm typ.) Table 1.
