General Description

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 than its predecessor.
