Description

The LPS33K is an ultra-compact piezoresistive pressure sensor which functions as a

digital output barometer. The device comprises a sensing element and an IC

interface which communicates through I²C 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 LPS33K is available in a ceramic LGA package with metal lid. 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. Gel inside the IC

protects the electrical components from harsh environmental conditions.
