STMicroelectronics LPS33W MEMS Pressure Sensors

STMicroelectronics LPS33W MEMS Pressure Sensor is ultra-compact and a digital output barometer. The LPS33W combines a sensing element and an IC interface, communicating through I2C or SPI from the sensing element to the application. Detecting absolute pressure, the sensing element consists of a suspended membrane manufactured using a dedicated process developed by ST. The LPS33W is available in a ceramic LGA package with a metal lid and 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, and the gel inside the IC protects the electrical components from harsh environmental conditions.
