Product overview
Description
The LPS22DF is an ultracompact, piezoresistive, absolute pressure sensor that 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 that communicates over an I²C, MIPI I3CSM, or SPI interface 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.
