Typical specifications are not guaranteed. 2 Cross-axis sensitivity is defined as coupling between any two axes. 3 Bandwidth is half the output data rate. 4 Turn-on and wake-up times are determined by the user defined bandwidth. At 100 Hz data rate the turn-on/wake-up time is approximately 11.1 ms. For additional data rates the turn-on/wake-up time is approximately τ + 1.1 in milliseconds, where τ is 1/(Data Rate). |
