12bit it IS then. :-)

Precisely my point. All the datasheet says is :
1. It is +/-2G mode --> so Numerator is 4G.
2. We are using 12bits --> so Denominator is 2^12 = 4096.
There is no clear reason/justification as to why 12bits was chosen

Had been through the application note earlier. The table5 (on page 12)

Hmmm. Interesting. As i understand LIS331DLH provides 16bit data
irrespective of the full-scale/sensitivity configuration. Hence we
could effectively map +/-2G to +/-32768(signed 16bit 2's complement).
According to the current-patch right-shifting the register values by
4(i.e. reducing 16bit --> 12

Hi All,
A few nitpicks.

Shouldn't it be "1LSB is 4000/1024 mG" ?
Also "outdata in 12bits" (typo. in->is?)
