HMC5883L
Configuration Register B
The configuration register B for setting the device gain. CRB0 through CRB7 indicate bit locations, with CRB denoting the
bits that are in the configuration register. CRB7 denotes the first bit of the data stream. The number in parenthesis
indicates the default value of that bit.
The table below shows nominal gain settings. Use the “Gain” column to convert counts to Gauss. Choose a lower gain
value (higher GN#) when total field strength causes overflow in one of the data output registers (saturation).

Description
Gain Configuration Bits. These bits configure the gain for
the device. The gain configuration is common for all
channels.
These bits must be cleared for correct operation.
