Description

The LPS33HW 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 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 LPS33HW 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

water.
