LPS22HH High-performance MEMS nano pressure sensor: 260-1260 hPa absolute digital output barometer Datasheet - production data Applications Altimeters and barometers for portable devices GPS applications Weather station equipment Sport watches HLGA-10L e-cigarettes (2.0 x 2.0 x 0.73 mm) Drones Gas metering Features Description 260 to 1260 hPa absolute pressure range Current consumption down to 4 A The LPS22HH is an ultra-compact piezoresistive absolute pressure sensor which functions as a Absolute pressure accuracy: 0.5 hPa digital output barometer. The device comprises a Low pressure sensor noise: 0.65 Pa sensing element and an IC interface which SM High-performance TCO: 0.65 Pa/C communicates through IC, MIPI I3C or SPI from the sensing element to the application. Embedded temperature compensation The sensing element, which detects absolute 24-bit pressure data output pressure, consists of a suspended membrane ODR from 1 Hz to 200 Hz manufactured using a dedicated process SM SPI, IC or MIPI I3C interfaces developed by ST. Embedded FIFO The LPS22HH is available in a full-mold, holed Interrupt functions: Data-Ready, FIFO flags, LGA package (HLGA). It is guaranteed to operate pressure thresholds over a temperature range extending from -40 C to +85 C. The package is holed to allow external Supply voltage: 1.7 to 3.6 V pressure to reach the sensing element. High shock survivability: 22,000 g Small and thin package ECOPACK lead-free compliant Table 1.
