LPS22HH High Accuracy Pressure Sensor

STMicroelectronics' LPS22HH MEMS Nano pressure sensor with 260 hPa to 1260 hPa absolute digital output barometer

Image of STMicroelectronics' LPS22HH High Accuracy Pressure SensorSTMicroelectronics' LPS22HH is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. The device comprises a sensing element and an IC interface which 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 STMicroelectronics. The LPS22HH is available in a full-mold, holed LGA package (HLGA). It 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.
