To provide a digitally switchable current source, by means of which no dangerous current spikes are produced at the switching instants, two digitally controllable switching transistors (MNn1, MNn2) are arranged in series with at least two parallel-arranged transistors (MNn) which are controllable by means of an analog voltage, while one of the two switching transistors is switched with the relevant inverted control signal and each one of the two switching transistors (MNn1, MNn2) is arranged in the current circuit whose current is to be controlled by the current source.
