ABSTRACT:
A digital-to-analog converter which includes a plurality of flip-flops each temporarily storing the corresponding bit data of digital data to be converted into an analog signal and producing true and complementary outputs relative to the stored data, the true outputs from the respective flip-flops being added with each other by a first adder and the complementary outputs from the respective flip-flops being added with each other by a second adder, and a subtracter subtracting the output from the second adder from the output from the first adder to obtain a final analog signal.
