3.2.4 High-g accelerometer
Characteristic Value Notes
Range ±200 g -
Resolution 16-bit, 6.1 mg -
Sample rate 1600 Hz ±2% 1
Bandwidth 800 Hz 2
Noise 5 mg/
√
Hz -
Accuracy at 1 g TBC 3, 4
Table 6: High-g accelerometer specification
Notes
1. Each sample includes a timestamp for a reliable measurement of time independent of the sample rate
error. See Section 9 on page 31 for more information.
2. The maximum bandwidth is achieved when the message rate is equal to the sample rate. If the message
rate is less than the sample rate then samples are averaged. See Section 9 on page 31 for more
information.
3. The accuracy at 1 g is evaluated as the deviation of the measured magnitude of gravity for a 360°
rotation around the X, Y, and Z axis aligned to the horizontal axis.
4. Accuracy is specified for the calibrated temperature only. See Section 4 on the next page for more
information.
3.2.5 Temperature sensor
Characteristic Value Notes
Range -104°C to 150°C 1
Sample rate 5 Hz ±0.3% 2, 3
Accuracy ±1°C at 25°C -
Table 7: Temperature sensor specification
Notes
1. The temperature sensor measurement range exceeds the device operating temperature range. See
Section 3.1 on page 9 for more information.
2. Each sample includes a timestamp for a reliable measurement of time independent of the sample rate
error. See Section 9 on page 31 for more information.
3. The temperature sensor is oversampled and the result decimated to the specified sample rate.
