Description
The LPS22DF is an ultra-compact piezoresistive absolute pressure sensor which
functions as a digital output barometer. The LPS22DF 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 LPS22DF 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.

Applications
• Altimeters and barometers for portable devices
