BMA180

Triaxial, ultra-high performance 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 full 14 bit

operation within a wide operation range

- 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, 3mm x 3mm

footprint, 0.9 mm height

- 256 bit EEPROM for calibration data and customer data

- Low power: typically 575 µA current even in 14 bit operation mode

- Very low-voltage operation: +1.8V . . . +3.6V for V

, +1.2V . . . +3.6V for V

DDIO

- Temperature range: -40 °C . . . +85°C

- RoHS-compliant, 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: 75µg/√Hz in low-noise mode

- 0.25mg accuracy in 2g-mode (14 bit operation, bandwidth=10Hz)

- Offset:

- Initial offset at room temperature (+25°C): < 4mg (incl. fine-offset)

- Very small Temperature Coefficient of Offset (TCO):

<0.35mg/K for x-/y-channel; <0.75mg/K for z-channel

- Sensitivity:

- Very small sensitivity tolerances @+25°C: < ±3.5%

- Very small Temperature Coefficient of Sensitivity (TCS): <±1.5% over

temperature range ±60K with respect to 25°C.
