Description：

The LPS27HHTW is an ultra-compact piezoresistive absolute pressure sensor whichfunctions as a digital output barometer. The device also embeds a temperaturesensor to monitor ambient temperature. The LPS27HHTW comprises a sensingelement and an IC interface which communicates through I²C, MIPI I3CSM or SPIfrom the sensing element to the application.The sensing element, which detects absolute pressure, consists of a suspendedmembrane manufactured using a dedicated process developed by ST.The LPS27HHTW is available in a ceramic LGA package with metal lid. It isguaranteed 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. Gelinside the IC protects the electrical components from water and the metal cap isgrounded electrically for better ESD robustness.
