1. An integrated circuit, comprising:
a DAC configured to output an analog signal;
an output terminal; and
an output stage arranged to receive the analog signal from the DAC,
wherein the output stage is configured to operate in a first mode to supply the analog signal to the output terminal as a first signal type, and in a second mode to supply the analog signal to the output terminal as a second signal type;
wherein the output stage includes first shared circuitry, first mode circuitry and second mode circuitry, wherein the integrated circuit is configured to combine the first shared circuitry with the first mode circuitry in a first mode, and combine the first shared circuitry with the second mode circuitry in a second mode, wherein the first mode circuitry and the second mode circuitry are arranged between an output of the first shared circuitry and the output terminal.
