... ADIS16209 THEORY OF OPERATION The ADIS16209 tilt sensing system uses gravity as its only stimulus, and a MEMS accelerometer as its sensing element. MEMS accelerometers typically employ a tiny, spring-loaded structure that is interlaced with a fixed pick-off finger structure. The spring constant of the floating structure determines how far it moves when subjected to a force ...

... Figure 4 provides the bit sequence for accessing the register memory structure. Each function within the ADIS16209 has its own register, which has a unique, 6-bit address. Note that all 16 SCLK cycles are required for the DIN bit sequence to configure the output for the next data frame ...

... Digital Filtering section). The factory calibration restore sets the offset null registers (XACCL_NULL, for example) back to their default values. CALIBRATION REGISTERS The ADIS16209 incorporates an extensive factory calibration and provides precision acceleration, incline, and rotational position data. For systems that require on-site calibration, user-programmable offset adjustment registers are available. ...
