Analog output circuit and inverter including same

An inverter which is an inverter that comprises an analog output circuit that outputs a bi-directional analog signal, the analog output circuit comprising:

• an operational amplifier (Op-Amp) that amplifies the difference between a first input node connected to a line of an output voltage and a second input node connected to a line of an offset voltage, and outputs a bi-directional analog signal from an output node;
• a first switch unit having one end connected to the first and second input nodes and the other end connected to the ground to switch between the one end and the other end;
• and
• a control unit that generates a control signal for controlling switching of the first switch unit,
• wherein when the first switch unit is in an OFF state, the output voltage and the offset voltage are respectively applied to first and second input nodes, and when the first switch unit is in an ON state, the first and second input nodes operate to be in a ground state.
