LPS28DFWTR

LPS28DFWTR is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. This device comprises a sensing element and an IC interface that communicates over the I²C or MIPI I3CSM interface from the sensing element to the application. It provides lower power consumption, achieving lower pressure noise than its predecessor. The package is holed to allow external pressure to reach the sensing element. Gel inside the IC protects the electrical components from water and the metal cap is, optionally, connected to ground or left floating electrically in the application PCB layout. The connection of the metal cap is determined according to the customer’s target application. It is used in applications such as wearables, altimeters and barometers for portable devices, GPS applications, weather station equipment, sport watches, e-cigarettes, water depth monitoring.
