Description
The LPS35HW 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 LPS35HW is available in a holed ceramic
LGA package. 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.
