Abstract
In a digital-to-analog converting device for converting an input digital signal into an output analog signal, a converting circuit converts the input digital signal into a first and a second digital signal which are alternatingly produced in parallel in response to clock pulses. A first and a second decoder are for decoding the first and the second digital signals into a first and a second decoded parallel digital signal. A first and a second parallel-serial converter are for converting the first and the second decoded parallel digital signals into a first and a second serial digital signal in response to an oversampling clock pulses. A first and a second digital-to-analog converter are for converting the first and the second serial digital signals into a first and a second analog signal. An analog adder adds the first and the second analog signals into a sum analog signal. An analog integrator is for integrating the sum analog signal into the output analog signal.
