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.
