  • 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.

    Key Features

    • Pressure sensor with water resistant package
    • 260 to 1260 hPa absolute pressure range
    • Current consumption down to 3 µA
    • High overpressure capability: 20x full scale
    • Embedded temperature compensation
    • 24-bit pressure data output
    • 16-bit temperature data output
    • ODR from 1 Hz to 75 Hz
    • SPI and I²C interfaces
    • Embedded FIFO
    • Interrupt functions: Data Ready, FIFO flags, pressure thresholds
    • Supply voltage: 1.7 to 3.6
    • ECOPACK® lead-free compliant
