Digital/analog converting circuit. |
摘要 |
A digital/analog converting circuit wherein, on the digital signal input side of each of resistances D1, D2 ... Dn whose one end being connected to a digital signal input and the other end to an analog signal output, each of the three-state non-inverting buffers B1, B2 ... Bn is provided, and between the analog signal output side of the resistance Dn and the ground potential portion, a MOS transistor 20 is provided. It enables to switch the output/non-output of an analog signal obtained by converting a digital signal, and as a result, a digital/analog converting circuit not generating non-linear region in the digital/analog conversion characteristic can be obtained. <IMAGE> |
