In an embodiment, a circuit is disclosed comprising a circuit portion coupled to a terminal and a calibration circuit portion coupled to said terminal.

Circuit with calibration circuit portion

An integrated circuit includes an output terminal to be coupled to a light-emitting diode, an output circuit coupled to the output terminal, the output circuit being configured to supply an operating signal to the light-emitting diode, a measuring circuit coupled to the output terminal and a control circuit coupled to the measuring circuit. The measuring circuit is configured to sense on the output terminal a signal value outside an operating regime of the light-emitting diode, the signal value being a voltage below a forward voltage of the light-emitting diode or a current below a threshold current of the light-emitting diode. The control circuit is configured to configure at least one function of the integrated circuit when the signal value as sensed by the measuring circuit corresponds to a voltage below the forward voltage of the light-emitting diode or a current below the threshold current of the light-emitting diode.
