In a line driver an input current (IINN) feeds a node (K 1 ) which is connected to an input on an amplifier (OTA 1 ). A further input on the amplifier (OTA 1 ) has a reference voltage (VSGND) applied to it. The amplifier (OTA 1 ) controls a current source (MN 1 ) which outputs an output current (IOUTN). A current/voltage converter (R 1 ) is connected between the node (K 1 ) and the current source (MN 1 ). A voltage/current converter (R 2 ) is connected between the current source (MN 1 ) and a ground (VSS).
