The invention relates to a line driver, wherein an input current (IINN) feed s a node (K1) which is connected to an input of an amplifier (OTA1). A second input of the amplifier (OTA1) is supplied with a reference voltage (VSGND). The amplifier (OTA1) controls a current source (MN1) which supplies an outpu t current (IOUTN). A current-voltage converter (R1) is connected between the node (K1) and the current source (MN1), and a voltage-current converter (R2) is connected between the current source (MN1) and ground (VSS).
