ABSTRACT:
The disclosure relates to an integrated circuit including an internal supply circuit. In the disclosed circuit, an analog voltage output circuit enables the connection of an output of this internal supply circuit to a connection pin of the integrated circuit. It is thus possible to make measurements, without difficulty, of the value of the internal voltage produced. The analog voltage output circuit is arranged in such a way that it is possible, firstly, to enforce a voltage from outside on the output of the internal supply circuit and, secondly, to insulate the output of the internal supply circuit from the connection pin.
