STMicroelectronics LPS22HH MEMS Nano Pressure Sensor

STMicroelectronics LPS22HH MEMS Nano Pressure Sensor is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device comprises a sensing element and an IC interface that communicates through I2C, MIPI I3CSM, or SPI from the sensing element to the application. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST. The LPS22HH is available in a full-mold, holed LGA package (HLGA). This sensor 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.
