Abstract
The evaluation circuit has a current interface (,′) for a current signal (i,) from an electronic signal transducer (,′); a current-sensing FET (,′) having a gate (G), a source (S), a drain (D) and a sensing output (sense), which is connected so that the current signal from the transducer passes through the source and drain; a monitoring circuit (,′) for controlling the current-sensing FET in the event of a malfunction connected between the gate (G) and to the drain (D) or source (S); a current reflector circuit (,′) having an input connected to the sensing output (sense) of the current-sensing FET and a resistor (,′) for converting current to voltage, which is connected to an output of the current reflector circuit, so that the current signal is converted to a voltage signal tapped between the resistor and the current reflector circuit.
