STMicroelectronics LPS28DFW Absolute Digital Output Barometer

Added to your shopping cart

STMicroelectronics LPS28DFW Absolute Digital Output Barometer is an ultra-compact piezoresistive absolute pressure sensor that operates as a digital output barometer. The LPS28DFW combines a sensing element and an IC interface which communicates over the I²C or MIPI I3CSM interface from the sensing element to the application.

The STM LPS28DFW Absolute Digital Output Barometer features a lower power consumption, achieving lower pressure noise than its predecessor. The LPS28DFW has been designed to meet the requirements and mission profile for personal electronics and consumer applications.

The device operates over a temperature range extending from -40°C to +85°C in a ceramic LGA package with a metal lid.
