Description：

The LPS22DF is an ultra-compact piezoresistive absolute pressure sensor whichfunctions as a digital output barometer. The LPS22DF provides lower powerconsumption, achieving lower pressure noise than its predecessor.The device comprises a sensing element and an IC interface which communicatesover I²C, MIPI I3CSM or SPI interfaces from the sensing element to the applicationand supports a wide Vdd IO range for the digital interfaces as well. The sensingelement, which detects absolute pressure, consists of a suspended membranemanufactured using a dedicated process developed by ST.The LPS22DF is available in a full-mold, holed LGA package (HLGA). 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.
