Digital absolute barometric pressure sensor measures 300 to 1100 hPa over an operating temperature range of -40 °C to +85 °C. The device uses a compact 8-pin metal-lid LGA package with a 2.0 mm × 2.5 mm footprint and 0.95 mm height. It supports I²C up to 3.4 MHz and 3-wire or 4-wire SPI up to 10 MHz. Low-power operation draws about 2.8 µA in 1 Hz forced mode, with 0.1 µA typical sleep current. The sensor is RoHS compliant, halogen-free, and rated MSL 1.
