Notes:
1. Resolution and acceleration ranges are user selectable via I
2
C or SPI
2. Sensitivity is proportional to BRES in BUF_CNTL2.
3. Requires changing of STPOL bit in INC1 register to 1 prior to performing self-test
4. Signal bandwidth varies with Output Data Rate (ODR), and Low Pass Filter setting.
Measured with ODR = 25600Hz, LPRO = 1 settings.
5. Noise varies with ODR, power mode, and the Average Filter Control (AVC) settings.
Measured with RES = 1, ODR = 50Hz, IIR_BYPASS = 0, LPRO = 1 settings.
