Abstract:
1. An output circuit comprising: a first output unit supplying a first voltage; a second output unit supplying a second voltage; a switching unit selectively outputting, to an output end, the first voltage from the first output unit and the second voltage from the second output unit; a detection unit detecting a voltage of the output end, wherein the detection unit includes a first detection unit and a second detection unit, the first detection unit detects a voltage of the output end when the first voltage from the first output unit is output to the output end, the second detection unit detects a voltage of the output end when the second voltage from the second output unit is output to the output end, and the control unit controls the first voltage on the basis of a voltage detected by the first detection unit, and controls the second voltage on the basis of a voltage detected by the second detection unit; and a control unit controlling one of the first voltage and the second voltage on the basis of the voltage detected by the detection unit.
