Could somebody please explain what the LSM303DLHC low-power and high resolution modes do? The data sheet has very little information. Is it different from the older version LSM303s? What is the change in power consumption?
Page 15 has:
I assume BW means bandwidth, but of what?
Page 15 also has:
and there is a high resolution enable bit in CTRL_REG4_A. But what does it do?
Unfortunately, we do not really have any additional information about the LSM303DLHC beyond what is in the datasheet. In low-power mode, the frequency in which the data gets recorded is lowered and we observed the resolution decrease by 2 bits. The frequency at which the data rate can be set to is shown in Table 20. For normal operation (high resolution), you have to set CTRL_REG4 bit high.
