LPS22HB MEMS Nano Pressure Sensor Absolute Digital Output Barometer

The LPS22HB 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 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 LPS22HB is available in a full-mold, holed LGA package (HLGA). 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 - 260 to 1260 hPa absolute pressure range - Current consumption down to 4 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 V - High shock survivability: 22,000 g - Small and thin package - ECOPACK lead-free compliant
