Description
The LPS22HH is an ultra-compact piezoresistive
absolute pressure sensor which functions as a
digital output barometer. The device comprises a
sensing element and an IC interface which
communicates through I²C, MIPI I3CSM 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 ST.
The LPS22HH 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.
