Zusammenfassung: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).
