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.
