A bias voltage (Vb) or an analog input signal (Sin) is selectively applied to a corresponding signal input terminal of the ladder circuit (50) by means of switches (S.sub.1 to S.sub.n) in response to control data (b.sub.1 to b.sub.n) of n bits. At least one of the resistance values of the two resistors (7, 8) of the final stage ladder portion is changed as a function of the state "0" or "1" of the final bit (b.sub.n ) of the control data, whereby the ratio of the output to the input of the ladder-type signal attenuator with respect to the control data is approximated in a polygonal line manner to a desired curve.
