The invention is based on the object of specifying a controllable resistor network which exhibits a wide dynamic range and at the same time only a small relative resistance increment size. According to the invention, this object is achieved by a controllable resistor network (40) in which the respective resistance value of the resistor network can be selected from a predetermined group of discrete resistance values by means of control signals (XXX, YYY) which can be applied to the resistor network, the graduation of the resistance values exhibiting a logarithmic or quasi-logarithmic characteristic.
