LPS22DFTR

LPS22DFTR is a low-power and high-precision MEMS nano pressure sensor, absolute digital output barometer. It is an ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer. This provides lower power consumption, achieving lower pressure noise than its predecessor. The device comprises a sensing element and an IC interface which communicates over I²C, MIPI I3CSM or SPI interfaces from the sensing element to the application and supports a wide Vdd IO range for the digital interfaces as well. The sensing element, which detects absolute pressure, consists of a suspended membrane manufactured using a dedicated process developed by ST. The package is holed to allow external pressure to reach the sensing element. Typical applications are altimeters and barometers for portable devices, GPS applications, weather station equipment, sport watches, e-cigarettes, drones, gas metering.
