I use the ADXL357 and just wan to get the Z-Axis's data.(Based on the TI CC3200 to develop it.)
The question is, I found that the output is 20 bits in total(fig.1),
but the range of output data just between 47,104~55,296(about 16 or 17 bits)
so this problem limited the data processing.
I want to know the relations bewteen the data range(47,104~55,296) and the '20 bits',
and if possible, please tell me how they exchange and convert.
*The words in the fig.3 are 'X-Axis, Y-Axis, and Z-Axis Sensitivity ±10 g 47,104 51,200 55,296 LSB/g'
*The images are from the datasheet about ADXL357
Hi, the range that you list here is for the part by part sensivitiy variation.
In +/-10gee range, the typical sensitivity is 51200 LSB/gee but some part may has the sensivity 47104 LSB/gee, some part may has the sensivity 55296 LSB/Gee.
Of course, these are min and max value. Most part should have the typical value.
Hope these can help.
