A difference amplifier circuit has two transistors (AT1,AT2) coupled by their emitters and whose base terminals form inputs for a differential input voltage (Ud) and whose collector terminals form outputs (out) for a differential output current (delta Ic) of the difference amplifier circuit. An additional transistor (ZT1,ZT2) is connected parallel to the transistors (AT1,AT2) relative to their base and emitter terminals. The collector terminals of the additional transistors are connected to the collector terminal of one of the coupled transistors (AT1,AT2).
