FXOS8700CQ - lnoise

Hello.

In register  CTRL_REG1 of the FXOS8700CQ acceleration sensor, there is the option lnoise. The manual states the following...

Reduced noise and full-scale range mode (analog gain times 2).
0 – Normal mode
1 – Reduced noise mode; Note that the FSR setting is restricted to ±2 g or ±4 g mode. This feature
cannot be used in ±8 g mode.

 

When arming that bit at a range of +-2g, is the resolution of  0.244 mg/LSB stays the same or it is being halved (0.122 mg/LSB)?

Does this reduced noise mode has to do anything with oversampling (OSR)?

 

Thank you very much.
