<p>A digital to analog converting apparatus is provided, which converts an analog output voltage into a digital value and compares the digital value with a digital input value, thus correcting the analog output voltage according to the result of the comparison. The apparatus has a current source (26, 28) for supplying current according to the result of the comparison and a capacitor (30) which is charged and discharged by the current from the current source (26, 28). The output voltage of the capacitor (30) is produced as the analog output voltage.</p> |
