    Abstract: The present disclosure relates to a driving circuit including a first circuit, a transistor switch, and a voltage level conversion circuit. The first circuit includes an operational amplifier and a feedback circuit, and is configured to output a first signal (e.g., an analog signal). The feedback circuit is configured to feed back the first signal to the operational amplifier. A source terminal and a drain terminal of the transistor switch are respectively electrically coupled to the operational amplifier and an output pin of the driving circuit. The voltage level conversion circuit is connected to the source terminal and a gate terminal of the transistor switch. When the voltage level conversion circuit is enabled, a voltage difference between the gate terminal and the source terminal of the transistor switch is controlled to a set value, so that the first signal is output to the output pin through the transistor switch.
