http://43zrtwysvxb2gf29r5o0athu.wpengine.netdna-cdn.com/wp-content/uploads/2015/02/MPU-9250-Datasheet.pdf (page 9) tells me that the accelerometer's Low Pass Filter response has a maximum of 260 Hz.
But http://43zrtwysvxb2gf29r5o0athu.wpengine.netdna-cdn.com/wp-content/uploads/2015/02/MPU-9250-Register-Map.pdf (page 15) tells me that I can get up to 460 Hz bandwidth (by setting ACCEL_FCHOICE=1 and A_DLPF_CFG=0)
So what is the maximum acceleration rate I can measure with this device? 260 Hz or 460 Hz?
