Abstract
A line driver switching stage includes a terminal for a reference potential, a terminal for a supply potential, and an output terminal of the line driver switching stage. A differential amplifier has a first and a second amplifier branch. The first amplifier branch has a resistor with first and second terminals. The first terminal of the resistor is the terminal for the reference potential. An emitter follower transistor has an emitter and has a base-to-emitter path connected between the second terminal of the resistor and the output terminal. A saturation prevention element has a first terminal connected to the output terminal and a second terminal connected to the second amplifier branch. A bipolar transistor has a base-to-emitter path connected between the second terminal of the saturation prevention element and the terminal for the supply potential. The bipolar transistor has a collector connected to the emitter of the emitter follower transistor.
