产品概要
描述
The LPS27DEWO is an ultracompact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device comprises a sensing element and a digital interface, which communicates over the I²C, MIPI I3C®, or SPI interface from the sensing element to the application. The LPS27DEWO provides lower power consumption, achieving lower pressure noise than its predecessor.
The LPS27DEWO is available in an LGA package with a metal lid. It is guaranteed 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. 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.
This device has been designed to meet the requirements and mission profile for personal electronics and consumer applications.
