- 260 to 1260 hPa absolute pressure range
- Current consumption down to 4 μA
- Embedded temperature compensation
- High-performance TCO: 0.65 Pa/°C
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.
