NOSDAC.............不响

小蓝

第一次做DAC-----东拼西揍的DD:数字接收(8414)+(74HC02)完全按照飘版的,DAC(PCM1702)LPF和公版的一样..............结果不出声+打击很大[em00]

NOSDAC.............不响

田雨

但给你的回报却远远超出这个价值。
对于AD1853这个1BIT结构的DAC，在听感上是不能与1702相比的。

小蓝

在广州的烧友那抢到一片AD1853[em09]..................改做1853了

期待你的好消息!!!

是呀，重新再做，加DF[em11]

田雨

1702玩NOS太浪费了，我以前曾做过带DF的，用SM5813，声音饱满，很有感染力，只要I/V及LPF做的好，是非常不错的。

小蓝

是1865的[em11]谢谢鬼版..............我在找相关电路[em11]

小鬼头

中间的逻辑接口电路相对比较复杂.一块HC02搞不定,我记得有老外贴过那接口图,需要五六块通用逻辑IC之多.....我估计你用的线路是给1865的.[em02]

是PCM1702,小鬼头版主的逻辑接口是否指74HC02???请指教,谢谢!!
HQ我是广州的..............请问什么去你家[em11]

我也要去HQ版家参观

小蓝

鬼版主8414+74HC02是按照AUDIONOTE的KIT 1.1做的!!!!!接入DVD的同轴时出现有规律的杂音,不接的时候就没有[em08]

是PCM1702,小鬼头版主的逻辑接口是否指74HC02???请指教,谢谢!!
HQ我是广州的..............请问什么去你家[em11]

小鬼头

若是PCM1702的话,接成NOS DAC还要加元件做逻辑接口.

若是AD1865的话,找AUDIONOTE的KIT 1.1(?)线路核对一下.
