LSM9DS0和LSM9DS1的加速度灵敏度混淆

加速度的所有灵敏度值都适合16位，但是16 g不能。
让我们使用FS 2g作为示例灵敏度级别。范围是-2到+2，这将是总共4g。或4,000 Milli-Gs。

输出为16位。 16位等于65,535。这意味着我们可以获得65,535个不同的读数，范围在-2和+2之间。 （或-2,000 MilliGs和+2,000 MilliGs）4,000 MilliGs / 65,535 = 0.061
0.061是数据表中的内容

这是所有灵敏度级别的值;

有人可以解释为什么会这样吗？

以下为原文




All the sensitivity values for the acceleration fit within 16 bits, however  �16 g does not.
Let�s use FS �2 g as an example sensitivity level.  As the range is -2 to +2, this would be a total of 4g.  Or 4,000 Milli-Gs.

The output is 16 bits. 16 bits equals 65,535.   This means we can get 65,535 different readings for the range  between -2 and +2. (or -2,000 MilliGs and +2,000 MilliGs)4,000 MilliGs / 65,535 = 0.061
0.061 is what is seen in the datasheet for
�2

here are the values for all sensitivity levels;

The only one that doesn't match up with the datasheets for both LSM9DS0 and LSM9DS1 is for
�16.  The calculations above show , but the datasheets have

Can someone please explain why this is so?
