Abstract
The invention relates to an integrated circuit arrangement () comprising at least one digital-analogue converter () with a multitude of current-source transistors (N-N) arranged parallel to each other for providing current components (I-I) that in each case are predetermined in a fixed manner and are used to form an analogue current signal, wherein control inputs of the current-source transistors (N-N) can be subjected to a shared adjustment potential by way of an adjustment potential line (), which adjustment potential defines the individual current components (I-I), and comprising an adjustment circuit () for providing the adjustment potential at the adjustment potential line (). In order to drastically reduce interference, in particular noise, in the individual current components (I-I), the integrated circuit arrangement () comprises an external connection (), which is connected to the adjustment potential line () for connecting an external capacitor (C).
