I use ADXL345 and ADXL375 under a uC software, which was written for ADXL345.
The Datasheet for ADXL345 says about ±2g/±4g/±8g/±16g ranges and corresponding to these ranges 10/11/12/13bits resolutions.
The Datasheet for ADXL375 shows only one range ±200g and 13bits resolution. .
Inspite of the ADXL375 Datasheet's info, that Register 0x31 only state for bits D3:D2:D1:D0 is 1n11 (D3 is the Full resolution bit, D1:D0 are the Range bits), the ADXL375 reacts for D1:D0 and D3 change in the Register 0x31 the same way, as the ADXL345,
So, in reality ADXL375 also provides 4 ranges (±25g/±50g/±100g/±200g).
Does ADXL345 really need 4 ranges? May be, it is enough to use the range ±16g under 13 bits resolution, as for ADXL375, or vice versa, 4 ranges for ADXL375?
Or, may be, there is some unobvious difference between these accelerometers, concerning the range/resolution change?
