The invention is structured to add each output signal of a plurality of signal converters connected in parallel, after a common signal is inputted to and quantized in the above plurality of signal converters, having a noise generators which input noise generated utilizing random variables unrelated to each other to respective quantizers within the above plurality of signal converters, so that quantization noise, Q, or the like can be effectively averaged, and a highly reliable signal conversion device, which can ensure an enough dynamic range across a wide frequency region, can be provided. Also, the invention is structured to add each output signal of a plurality of signal converters connected in parallel, after a common input signal is inputted to and quantized in the above plurality of signal converters, so that a highly reliable signal conversion device similar to the above can be provided.
