BMA180
Triaxial, ultra high performance digital accelerometer with switchable g-
ranges and bandwidths and integrated thermometer
Key information
- Three-axis accelerometer with integrated temperature sensor
- Ultra high performance g-sensor (ultra-low noise, ultra-high accuracy) with 14 bit ADC
operation
- Digital Interfaces: 4-wire SPI, I²C, interrupt pin
- High feature set with customer programmable g-ranges, filters, interrupts, power modes,
enhanced features, in-field calibration possibility for customers and self-test capability
- Standard SMD package: LGA package, 3 x 3mm2 footprint, 0.9mm height
- 256 bit EEPROM for calibration data and customer data
- Low power: typically 650μA current even in 14 bit operation mode
- Very low-voltage operation: +1.62V … +3.6V for VDD, +1.2V … +3.6V for VDDIO
- Temperature range: -40°C … +85°C
- RoHS compliant and halogen free
- No external components needed besides 1 standard blocking capacitor for power supply
- Process based on automotive-proven Bosch Silicon Surface Micromachining
Key performance (all typical values)
- Resolution/noise:
- Ultra-low noise: 150μg/√Hz in low noise mode
- 0.25mg ADC-resolution in 2g-mode
- Offset:
- Offset at room temperature (+25°C): 4mg (incl. fine-offset tuning)
- Very small Temperature Coefficient of Offset (TCO): 0.25mg/K
- Sensitivity:
- Very small sensitivity tolerances @ +25°C: ±1.5%
- Very small Temperature Coefficient of Sensitivity (TCS): ±0.01%/K
