Integrated circuit comprising a digital-to-analog converter

An integrated circuit comprising:

• a digital-to-analog converter configured to convert a digital word into an analog signal,
• a switching circuit connected to an output of the digital-to-analog converter and configured to receive the analog signal, wherein the switching circuit includes:
• a PMOS-type first transistor having a drain and a source, wherein the drain is connected to the output of the digital-to-analog converter and configured to receive the analog signal generated by the digital-to-analog converter, and wherein the source is connected to a drain of a PMOS-type second transistor,
• a NMOS-type third transistor having a drain and a source, wherein the drain is connected to the output of the digital-to-analog converter and the drain of the PMOS-type first transistor and configured to receive the analog signal generated by the digital-to-analog converter, and the source is connected to a drain of a NMOS-type fourth transistor, and
• a voltage control circuit connected in parallel to the digital-to-analog converter and configured to receive the digital word and to apply a voltage on the source of the PMOS-type first transistor and on the source of the NMOS-type third transistor based on a value of the digital word, wherein the voltage applied on the source of the PMOS-type first transistor and on the source of the NMOS-type third transistor by the voltage control circuit is to limit a drain-source voltage of the PMOS-type first transistor and to limit a drain-source voltage of the NMOS-type third transistor regardless of the value of the digital word and the analog signal generated by the digital-to-analog converter based on the value of the digital word that is transmitted to the switching circuit.
