A digital-to-analog converter arrangement able to process input signals
with different signal bandwidth is provided. The arrangement comprises a
first input terminal for receiving a first digital input signal, a second
input terminal for receiving a second digital input signal and switching
means being coupled to the first and second input terminals and being
adapted to select between the first and second digital input signals so as
to output an intermediate digital signal corresponding to the selected one
of the first and second digital input signals. The intermediate digital
signal is received by an array of unary digital-to-analog converting
elements, each unary digital-to-analog converting element being adapted so
that, as an analog output signal, a sum signal of output signals of the
unary digital-to-analog converting elements is output.
