随着技术的不断进步,采用数字信号处理方式的AV设备也越来越多起来。CD机、VCD机等就是这样的设备。当需要将重放的数字信号还原成模拟信号时就离不开DA转换器,也称解码器。本文介绍一种制作简单、使用器件不多、音质好的DA转换器的制作方法。无需任何调整,只要连线不错就能正常工作。 一、设计概要 图1是DA变换器的基本组成。图2是本文介绍 表1 PCM58P的特性 With the continuous improvement of technology, the AV equipment adopting the digital signal processing method is also more and more. CD machine, VCD machine is such a device. When you need to replay the digital signal is restored to an analog signal is inseparable from the DA converter, also known as decoder. This article describes a production of simple, use less devices, good quality DA converter production method. Without any adjustment, as long as the connection is good will be able to work properly. First, the design summary Figure 1 is the basic composition of the DA converter. Figure 2 shows the characteristics of Table 1 PCM58P in this paper
