Zusammenfassung:The input stage (16) of a high-fidelity amplifier (10) with high linearity and a low distortion rate comprises:-an input (12) for the digital signal to be converted;-a voltage output (26) for the converted voltage;-a digital/analog converter (20), the input of which forms the input (12) for the digital signal to be converted, the digital/analog converter (20) having access to a signal terminal (24);-a voltage current conversion resistor (36) arranged between the voltage output (26) and a reference potential; and-a current/voltage converter (22) that has a voltage output and is arranged between the signal terminal (24) and the voltage outlet (26). The current/voltage converter (22) comprises a transistor (46). The source of the transistor (46) is only connected to the signal terminal (24) of the digital/analog converter (20).
