D/A conversion circuit

A digital/analog conversion circuit, comprising:

• a digital/analog conversion portion which outputs a first current and a second current in a differential relationship according to input digital signals;
• and
• first and fourth current mirror circuits which generate mirror currents according to the first and second currents for output as differential analog signals,
• the digital/analog conversion circuit converting the digital signals into the analog signals, and further comprising:
• a second current mirror circuit, which generates a first mirror current according to the first current;
• a third current mirror circuit, which is connected to a reference voltage, and to which the first mirror current is input, and which generates a second mirror current equal to the first current, according to the first mirror current, between the digital/analog conversion portion and the second current mirror circuit;
• a fifth current mirror circuit, which generates a third mirror current according to the second current;
• and
• a sixth current mirror circuit, which is connected to the reference voltage, and to which the third mirror current is input, and which generates a fourth mirror current equal to the second current, according to the third mirror current, between the digital/analog conversion portion and the fifth current mirror circuit.
