STMicroelectronics LPS22CH High-Performance MEMS Nano Pressure Sensor
STMicroelectronics LPS22CH High-Performance MEMS Nano Pressure Sensor is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The LPS22CH comprises a sensing element and an IC interface that communicates through I2C 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 LPS22CH MEMS Nano Pressure Sensor is available in a full-mold HLGA-10L package with a -40°C to +85°C operating temperature range. The package is holed to allow external pressure to reach the sensing element.
