Description

The LPS22CH 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 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 LPS22CH 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

 GPS applications

 Weather station equipment

 Sport watches

 e-cigarettes

 Gas metering
