MANUFACTURER DATA REVIEW
Key technical specifications
Ordering-code highlights reviewed against official manufacturer documentation.
- Function
- Digital barometric pressure sensor with temperature output · 10-pin metal-lid LGA, I2C and SPI interfaces
- Operating pressure range
- 300 hPa to 1250 hPa at full accuracy (Table 2; min/max over the full-accuracy temperature range 0 °C to +65 °C)
- Relative accuracy
- ±0.03 hPa typical (≈ ±25 cm) · 700 hPa to 1100 hPa, 25 °C to 40 °C, per 10 kPa steps (Table 2)
- Absolute accuracy
- ±0.50 hPa typical over 300 hPa to 1100 hPa at 0 °C to +65 °C; ±0.33 hPa typical at the 900 hPa, 25 °C point; ±0.40 hPa typical over 900 hPa to 1100 hPa at 25 °C to 40 °C (Table 2)
- Offset temperature coefficient
- ±0.62 Pa/K typical (mean value) · 900 hPa, 25 °C to 40 °C (Table 2; the Table 1 summary rounds this to ±0.6 Pa/K)
- Noise and resolution
- RMS noise 0.9 Pa typical at 25 Hz ODR with 32× pressure and 2× temperature oversampling; 0.02 Pa typical filtered at the lowest bandwidth; output resolution 0.016 Pa (Table 2)
- Temperature accuracy
- ±0.5 °C typical at 25 °C; ±1.50 °C typical over 0 °C to +65 °C (Table 2)
- Supplies
- VDD 1.65 V minimum / 1.8 V typical / 3.6 V maximum; VDDIO 1.2 V to 3.6 V (Table 2)
- Current consumption
- 3.2 µA typical average at 1 Hz, pressure + temperature, ultra-low-power oversampling (§3.8 Table 22 gives 3.2 µA typical / 7.4 µA maximum for that setting at 1 Hz forced mode); sleep 1.4 µA at 1.8 V rails; pressure-measurement peak 660 µA typical (Tables 1–2)
- Output data rate
- Up to 200 Hz at minimum oversampling; normal-mode rates prescale down to 0.0015 Hz (Tables 2 and 45)
- Interface rates
- I2C up to 3.4 MHz; SPI 3-wire and 4-wire up to 10 MHz (Table 1)
- Absolute maximum ratings
- Supply pins −0.3 V to +3.6 V, storage −45 °C to +85 °C and overpressure survivability 2,000,000 Pa are Table 3 maximum ratings — the overpressure figure is a survival limit, not the operating range
- Identification
- Single product identified by technical reference code 0 273 017 014; package marking is a lot counter plus the product digit — the data sheet defines no order-code variants (§7.3)
- Manufacturer packing
- Tape and reel, 10,000 per reel (§7.5) · MSL1, RoHS and halogen-free
