发明名称 D/A converter
摘要 A D/A converter formed on a semiconductor substrate includes a plurality of resistance strings which are provided between a low voltage terminal and a high voltage terminal, each of the resistance strings including a plurality of resistances connected in series. The resistance strings to be connected at odd-numbered positions are arranged on the substrate in order of increasing in a direction from a near side of the terminal to which the low voltage is applied to the far side thereof, and the resistance strings to be connected at even-numbered positions are arranged on the substrate in order of increasing in a direction from the far side of the terminal to the near side. A voltage at a junction point of the resistances constituting the resistance string is selectively output in accordance with input data to be converted.
