STMicroelectronics LPS33K MEMS Pressure Sensor

STMicroelectronics LPS33K MEMS Pressure Sensor combines a sensing element based on a piezoresistive Wheatstone bridge approach with an I²C interface in a single compact package. The sensing element detects absolute pressure and consists of a suspended silicon membrane. When pressure is applied, the membrane deflection induces an imbalance in the Wheatstone bridge, and the output signal is converted by the IC interface. The LPS33K features a data-ready signal that indicates when a new set of measured pressure and temperature data is available, simplifying data synchronization in the digital system that uses the device. STMicroelectronics LPS33K MEMS Pressure Sensor is available in a ceramic LGA package with a metal lid. The package is holed to allow external pressure to reach the sensing element, while the gel inside the IC protects the electrical components from harsh environments.
