A line driver (24), including a first amplifier (30A) having a first and a second input, and a first output coupled to a first side of the line. The driver includes a second amplifier (30B) having a third and a fourth input, and a second output coupled to a second side of the line. The driver includes a first feedback resistor (32A), connected between the first output and the second input, and a second feedback resistor (32B), connected between the second output and the fourth input. The driver includes a series resistor (38A, 38B), having a first side coupled to the first output and a second side coupled to the second output, and a gain resistor (40A, 40B) having a first side connected to the second input and a second side connected to the fourth input. The driver further includes current feedback resistors (36A, 36B), connected between the gain resistor and the series resistor.
