Abstract
A serial input digital-to-analog converting device suitable for converting an n-bit digital signal to an analog signal is disclosed, wherein the digital signal is early divided into m bytes and the converting device comprises m digital-to-analog converters for independently receiving the m bytes before converting the m bytes into corresponding analog voltages, a voltage divider capable of providing two voltages to each digital-to-analog converter so that each digital-to-analog converter can use the difference between the two received voltages as a dynamic voltage variation range for converting the m bytes and the difference between the two received voltages provided by the voltage divider to the kth digital-to-analog converter is (Δ V)/{2^[n(m-k)/m]}, and an adder for adding the analog voltages to generate the analog signal.
