adxl375在3200hz ODR设置下出现大量的毛刺,但是在100hz的odr却表现很好

Thread Summary

The user is experiencing increased noise and spikes in the output data of an ADXL372 accelerometer when the ODR is set to 3200 Hz, compared to 100 Hz. The final answer suggests ensuring the chip is in a vibration-free environment and checking the amplitude of the noise. It also recommends testing without the FIFO to rule out any data processing issues, referencing a known issue with FIFO data errors at high ODRs.
