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