The DPS368 is a miniaturized digital barometric pressure sensor that measures both pressure and temperature in a compact 8-pin LGA package. It operates from 1.7 V to 3.6 V, measures pressure from 300 hPa to 1200 hPa, and supports an operating temperature range of -40 °C to 85 °C. The sensor provides relative pressure accuracy of ±0.06 hPa, absolute accuracy of ±1 hPa, pressure precision of ±0.002 hPa, and temperature accuracy of ±0.5 °C. It communicates through I2C or SPI with optional interrupt support and integrates a FIFO. The package is environmentally protected against water, dust, and humidity with IPx8 resistance.
