Abstract

The circuit delivers a positive and negative output current and has push-pull power output stages. The control circuit (5) is directly connected to the base of a transistor (7) in the push-pull output stage (6, 7). Two diodes (3, 4) are in series between the bases of transistors (6, 7), and in parallel with a capacitor (16). A resistor (2) connected to the supply voltage (UB) is connected to the junction point between the capacitor (16) and the diode (3).
