LSM9DS0 +16g range

Posted on February 26, 2014 at 11:06I've set up the LSM9DS0 to the +/-16g range by setting AFS2 - 0 as 100 as per datasheet. Normal g comes out as 0.7g, yet all other ranges are fine. What am I doing wrong? Chris

clock stability, and sampling rate on LSM9DS0

Posted on October 26, 2013 at 09:15There are no figures for clock stability over time and temperature. These are going to effect the sample rate times. For example, if the accelerometer DOR is 100Hz, what spread can be expected. I take it that in al...
