STMicroelectronics' LPS33W is an ultra-compact piezoresistive pressure sensor which functions as a digital output barometer. The device is comprised of a sensing element and an IC interface which communicates through I2C or SPI from the sensing element to the application.
The sensing element detects absolute pressure and consists of a suspended membrane that is manufactured using a dedicated process developed by STMicroelectronics.
The LPS33W is available in a ceramic LGA package with a metal lid. The device operates 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 harsh environmental conditions.
