3.5.4.4 Resolution
The analog interface is internally sampled and processed by a digital micro-controller. This causes a limited resolution of
analog steps. The effective resolution is the same for set values (VSEL etc.) and actual values (VMON/CMON). It’s 26214
steps when working in the 10 V range. In the 5 V range this resolution halves. Due to tolerances, the truly achievable resolution
can be slightly lower.
