LPS28DFW - STMicroelectronics

LPS28DFW absolute digital output barometer

The LPS28DFW is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which communicates over the I²C or MIPI I3CSM interface from the sensing element to the application. The LPS28DFW provides lower power consumption, achieving lower pressure noise th.
