摘要
介绍高性能音频数模转换器件WM8741的基本特性。设计一种基于WM8741及数字音频接收器件CS8416的音频解码电路,并给出CS8416与WM8741的接口设计。该解码器由数字音频接收、数模转换以及模拟信号调理等模块组成,最高支持字长为24位、频率为192 kHz的数字音频信号输入。
The features of high performance stereo DAC WM8741 is introduced. A design of audio decoder circuit based on WM8741 and CS8416 is presented,and the audio interface between CS8416 and WM8741 is described. The decoder, which includes digital audio receiver,digital to analog converter and signal condition circuit, supports input data word length up to 24-bit and sampling frequency up to 192kHz.
