

Write accesses to the SOFF/COFF/SGAIN/CGAIN register serve for pre-setting - these registers are

permanently updated by the internal automatic gain-offset-controller.

The scaling factor indicated applies to the behaviour of the adjustment register; it does not describe the

maximum signal error possible.
