ST LPS25HTR

АбсолютI²C, SPI1,7 В ~ 3,6 В

Overview

This is an ultra-compact absolute piezo-resistive pressure sensor with a high-resolution sensing element and embedded temperature compensation. Digital pressure, temperature data and register control communication is through the SPI and I²C interfaces. The pressure sensors are designed with “ST’s VENSENS technology” allowing the fabrication of pressure sensor on a monolithic silicon chip. This will eliminate wafer-to-wafer bonding and maximise reliability. These pressure sensors use innovative MEMS (Micro Electro-Mechanical Systems) to provide an extremely high pressure resolution in an ultra-compact and thin package. Pressure sensors are becoming increasingly used in tablets, smartphones, and wearable technology. With them becoming increasingly popular in smartphones, it opens the door to new applications such as weather analysers, health and sports monitors.

• Key technical features – • Enhanced temperature compensation • Absolute pressure range from 260 to 1260 hPa• Lower power consumption, less the 4μA• Pressure noise lower than 1Pa RMS• Embedded FIFO
