Filed: 1979-09-28
Abstract: The DA converter has seven resistors (70, 76) connected between the input (VREF) terminal (77) and earth. The upper part of the convertor uses resistors (70-72) which form a resistance ladder for a two bit convertor including switches (78-83) connected as a branch network to terminal (84). The lower part uses resistors (73 to 76) forming a second ladder network for a second two bit converter using switches (85 to 90) connected as a branch network to terminal (91). The upper switch network receives the two highest weight bits (AB) of a four bit word. The lower weight bits (CD) are applied to the lower circuit. The lower resistance ladder is graduated to ensure balancing of a single bit with respect to the upper resistance ladder. When the two convertors each have two bits the four lower resistors each have a value R/4. The lower weight bit (D) of the word is applied to switches (87-88) and its complement (D) to switches (85-86). The bit (C) of the word of immediately higher weight to that of its bit of least weight is applied to switch (90) and its complement (C) to switch (89).
