    摘要: An input circuit arrangement comprises an input, a comparator, and an evaluation circuit. The input is designed for coupling to a first terminal of an impedance and for feeding an input signal. The comparator is connected to the input of the input circuit arrangement and is designed for delivering an activation signal to an output as a function of a comparison of the input signal with an adjustable threshold. Furthermore, the evaluation circuit is connected to the input of the input circuit arrangement and for its activation to the output of the comparator and is designed for evaluating the value of the impedance that can be connected.
