Abstract: PURPOSE: By it partials, medially eliminating error toward the input of digital data the digital to analog converter enhances the accuracy of the digital to analog converter. CONSTITUTION: It distributes to the before distribution class field of the plurality having the size of the reference current decision by discussion search the reference current which the electric current distribution part(20) is provided from the reference current route of supply source. According to the rotating exchange part is the control signal, the route of the before distribution class field having the route of being exchanged as described above is re-exchanged.

Abstract translation: 目的：通过内部消除数字数据输入的错误，数模转换器提高了数模转换器的精度。 构成：通过讨论从供应源的参考电流路径提供电流分配部（20）的参考电流，分配到具有参考电流决定大小的多个的前分发类场中。 根据旋转交换部分是控制信号，重新交换具有如上所述交换路线的分配前场的路线。
