MEMS Pressure Sensor: Absolute Digital Output Barometer in Water Resistant Package


  • Pressure Sensor in Water-Resistant Package
  • 260 to 1260 hPa Absolute Pressure Range
  • Current Consumption of 4 μA
  • Low Pressure Sensor Noise: 0.7 Pa

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. 

This integrated pressure sensor is available in a ceramic LGA package with a metal lid. It operates over a temperature range extending from -40 °C to +85 °C. A gel inside the IC protects the electrical components from water and the metal cap is grounded electrically for better ESD robustness.
