Abstract
The invention relates to an amplifier circuit () for a two-wire interface, comprising a first current path (), comprising a voltage-controlled current source (T) having a gate (GT), which is connected to an input connection (E) of the amplifier circuit. A second current path () of the amplifier circuit comprises a voltage-controlled current source (T), which is connected in series with the second resistor (R). The first resistor (R) and a parallel connection of the first and second current paths () are connected in series between an output connection (A) and a reference voltage connection (B) of the amplifier circuit. The amplifier circuit () makes it possible to adjust the gain and to provide a supply voltage and a useful signal over a common conducting track (L).
