Abstract

Circuit arrangement including an interface, a protection circuit and a measurement circuit. The interface is configured to receive a signal. The protection circuit is coupled to the interface. The protection circuit is configured to limit a voltage provided by the interface to a protection voltage. The measurement circuit is coupled to the protection circuit and configured to provide at least one of a signal of a first measurement type and a signal of a second measurement type if a voltage provided by the interface is higher than the protection voltage and configured to provide a signal of a second measurement type if the voltage provided by the interface is lower than the protection voltage.
