Abstract
An output buffer amplifier includes one end stage for small output capacities and one end stage for large output capacities. The end stages have outputs being connected to one another. A control stage is connected upstream of the end stage for small output capacities. The control stage has one input being triggered by a signal proportional to an input signal of the end stage for large output capacities and another input being triggered by a signal proportional to an output signal of the end stage for small output capacities.
