“心”做1543 DAC ！

雨衣妹妹

在DAC芯片庞大阵列中有一块颇具争议的芯片，那就是TDA1543。有DX会说那是个最便宜的芯片，用过的人有的也许会说～是我听过“最烂”的芯片，而小日本“楠亮平"说～在1543面前PCM63都要靠边，它是我做过最棒的芯片 http://www.tnt-audio.com/intervis/kusunoki_e.html  
    虽然以前也装过论坛一代老板1543，毕竟做的没有那么用心，出来后也很快被新欢所取代，所以一直都没有认真的听过和做过1543。想到这些不觉有股要重做1543冲动，根据1543的特点精心选元件还第一次采用了”红炮“电容，半天时间就做好了～嘻嘻！不要说我快，没有二下子怎么当版主呀。

“心”做1543 DAC ！

试听“心”做1543，我的器材是建伍8010～1543DAC～（论坛前级耳放＋豆版twinkle）～深海HD600。虽然8010算不上好的CD机，但转盘还算沉稳，声音经过调教也上了一个台阶，经过对比个人感到1543的音乐味，低音弹性和中音厚度均超过了8010，高音也少了不少“火气”解析力也在接受范围内。层次和解析力8010超越，还有1543DAC的人声比较靠前。 对于这个结果我是比较满意的，一百多元DAC只要用“心”做也会给你惊喜！
装好后的1543也只有数码宝这么大。

“心”做1543 DAC ！

本来想试试并联DAC但由于找不到1543也只能放弃，成为此次的遗憾。

那红炮是否施碧0.1μF200v的那种，用上去真的那么神奇？还有输出电容您用那种？

以前和这儿的网友讨论过,他们说Y5V的不是很好!听说对温度和湿度敏感,漂移比较大!但是,片状陶瓷能上到22U的就只有Y5V的!
我用的是从旧的硬盘上面拆的!反正耳朵听着好过我所见过的所有铝电解!
看看雨衣MM你的感觉怎么样吧!有的话试一下上来和大家谈感受!呵呵[em11][em05]

雨衣妹妹

当然还有大家的建议。

AKMY5

再和我们说说你的1543?
我正准备做呢?呵呵
好多年前就想试了!苦于没有图!和1311又不一样的!1311我觉得已经够爽的了!1543要是还好的话就更爽了!
我还没听过呀!

呵呵!还有更好的对比还没上,站个位先

下面上非记BC的图了!也是120HZ和1KHZ频率做对比,先上120HZ的
<img src="attachments/dvbbs/2005-5/20055923467434.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/20055923467434.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


1KHZ频率测的指标!
<img src="attachments/dvbbs/2005-5/200559234730482.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559234730482.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


大家对比一下上面的尼基科恩的和非记BC的吧!那个好?呵呵!我再把有关参数重复一遍!
尼基科恩的:
120HZ下:                D=0.043  容量=386.1U
1KHZ下:                  D=0.177  容量=362U

非记BC:
120HZ下:                D=0.054    容量=421.4U
1KHZ下:                 D=0.359    容量=361U

大家可以看出那个黑皮的尼基科恩还是很棒的!1000HZ下,容量才降了20几U,说明高频性能很棒!远强过非记的BC!!!不过我要和大家特别说明,这个黑皮的尼基科恩是在彩色显示器上拆的!要是一般的可就刚好反过来啦!我测过好几个!都不如非记BC!

下面我再上顶级的非记蓝皮吧!这个才牛啊![em11][em06][em06][em06]
同样先上120HZ测的图!
<img src="attachments/dvbbs/2005-5/20055100011617.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/20055100011617.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

再上1000HZ挡测试的!仔细对比一下指标!
<img src="attachments/dvbbs/2005-5/20055100234347.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/20055100234347.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />



最后介绍一下这个表吧!本应该开始就介绍的,那样大家好分辨,但是一兴奋发图发反了,将就吧!
它测电感和电容都有120HZ和1000HZ两个挡位,带品质因数显示!(电容是D,电感是Q)
<img src="attachments/dvbbs/2005-5/200551005717929.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200551005717929.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

对的，是ROE。说说理由，我想大家也想知道。

我上个图给你看吧!有测量的为证!

“心”做1543 DAC ！

下面就是我要对比给你看的ROE和非记的BC
<img src="attachments/dvbbs/2005-5/200559224556257.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559224556257.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


下面是我拍的表测的给大家看,请注意我的表的右上角的那一排数字,是品质因数!很重要!越低性能越好!最后我再上张我的表的说明!
<img src="attachments/dvbbs/2005-5/200559225155925.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559225155925.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />



来看ROE的!品质因数达0.7了!在1KHZ频率还有1500微,呵呵!过得去
<img src="attachments/dvbbs/2005-5/200559225536141.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559225536141.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


1000微的和2200微的比不公平!再上张也是2200微/25V的非记的BC吧
<img src="attachments/dvbbs/2005-5/200559225759853.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559225759853.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

呵呵!上面的两张图大家就可以看出性能区别的了!同样是2200微的容量,但是在1KHZ频率下,ROE还有1423微,D值=0.741
但是非记的BC蓝皮还有1577微,D=0.533     好很多啦!实际上我接到功放机器上面对比过!
ROE的不但高音难比蓝皮BC,就连低音也不好,很混!BC清澈好多!




题外话,我再上几个更好的对比给大家看吧!下面是我要对比的几种!

<img src="attachments/dvbbs/2005-5/200559231050729.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559231050729.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />


先上尼基科恩的!记住这和电视机上拆的是不一样的!这是电脑彩显拆的,电视的测得的指标没眼看!呵呵
120HZ频率测的,下面那张是1KHZ测,大家对比一下!
<img src="attachments/dvbbs/2005-5/200559231722263.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-5/200559231722263.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
1KHZ测的指标!大家对比!

我也来交流一下经验吧
我人为板子仅有一片IC供电时数字和模拟的分开隔离是提高信噪比的关键!
一般是用电感量大一点的磁珠,色码电感隔离后再就近在用电的IC的电源脚就近贴小电容和安装大电容,这样效果才好!
雨衣版就近使用电容很有水准!!![em06]佩服!建议你在背后贴0.1微的贴片的片状元件,效果更好!


我觉得最大的问题是这种磁珠还远不能达到隔离的目的!因为它的电感量太小了!只有0.5微H,要用电感量大一点的更好一些!象我下面后面的那张图里给的,一般都有几十到一百微H,那种两脚的树着的有几毫H,而且它的线径粗,直流内阻低,效果更好!要不用磁环自己绕也不错!

这样隔离后会造成电源的各路内阻稍大,但是没关系,再在各部分IC的电源脚端象雨衣MM那样就近装电容退偶就能重新改善!
