ABSTRACT:
In a circuit arrangement for converting a digital input signal into an analog output signal, comprising a voltage divider chain which, between its ends which are supplied by at least one reference voltage, has a plurality of taps which, under the control of the digital input signal, are connectable to an output for deriving the analog output signal, a reduction in the output resistance and also an increase of the bandwidth of the analog output signal are accomplished because of the fact that any possible value of the digital input signal (B0 . . . B7) connects at least two taps (A0 . . . A257) of the voltage divider chain (W1 . . . W257) together to the output.
