Infineon XENSIV™ DPS368 - ultra small waterproof pressure sensor

XENSIV™ DPS368 is a miniaturized digital barometric pressure sensor capable of measuring both pressure and temperature. It offers an ultra-high precision (±2 cm) and a low current consumption for precise measurement of altitude, air flow & body movements. Due to its robust package, it can withstand 50 m under water for one hour (IPx8) and protects the sensing cells against dust and humidity. Additionally, the robustness facilitates handling in assembly line.

Key features

• Package dimensions: 8-pin LGA, 2.0 x 2.5 x 1.1 mm3
• Waterproof: IPx8 (50m, 1 hour)
• Operation range: Pressure: 300 – 1200 hPa Temperature: -40 – 85 °C
• Precision: ± 0.002 hPa (or ±0.02 m)

Additional features:

• Rel. accuracy: ± 0.06 hPa (or ±0.5 m)
• Abs. accuracy: ± 1 hPa (or ±8 m)
• Temperature accuracy: ± 0.5°C
• Avg. current consumption: 1.7 μA (pressure measurement) @1Hz sampling rate, Standby: 0.5 μA.
• Integrated FIFO
• Interface: I2C and SPI (both with optional interrupt)
• Green Product (RoHS) Compliant
• Best-in-class resolution (±0.02 m) - precise measurement of altitude, air flow & body movements
• High measurement rate (up to 200Hz) & fast read-out - quick sensor feedback
• 50% less power consumption then competitor product when running in full speed due to capacitive technology (AC biasing) - longer battery lifetime
• Robust against water (IPx8, 50 m under water for 1 hour), dust & humidity - can be used in harsh environment & facilitates handling in assembly line
• Very small water resistant package (2.0x2.5x1.1 mm3) - space saving up to 80% compared to other waterproof pressure sensors

Applications

• Smart watches & wearables
• Home appliances
• Health care
• Drones
