STM Nano Pressure Sensor-LPS22DF MEMS

STM Nano Pressure Sensor-LPS22DF MEMS
STMicroelectronics LPS22DF nano pressure sensor is an ultra-compact piezoresistive absolute pressure sensor. The power consumption of LPS22DF is low, and the pressure noise is better than the previous generation products.
This device includes a sensor element and IC interface, communicates from the sensor element to the application program through I2C, MIPI I3CSM or SPI interface, supports various Vdd IO, can also be used for digital interface. The sensor element can detect absolute pressure, including a suspended membrane manufactured by a special process developed by ST.

STMicroelectronics LPS22DF is available in a fully molded through-hole LGA package (HLGA). The device is guaranteed to operate in the temperature range of -40°C to +85°C. The package is perforated to allow external pressure to reach the sensing element.
