Description

The LPS27HHW 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 LPS27HHW 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 and the metal cap is grounded electrically

for better ESD robustness.
