在找........这里也有一个

以下是引用小蓝在2006-2-25 16:07:00的发言：ADM707,我现在找不到
找个替代品好了啊
我图片上的元件你都齐了吗??
ADM707,我现在找不到AD1853的东东都准备好啦,有没有PCB
转块给我.听过朋友的1853确实好声.

有!!!!正常出声,我把OP的4.12K的电阻改成22K,可是声音还是很小!!!哪位DX帮看看OP应该什么改(我用5534代了AD797,没用上缓冲)????<img src="attachments/dvbbs/2006-3/20063481552940.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/2006-3/20063481552940.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />呵呵
有进展啦～～最新报告
解决了BUG1853的14脚电压问题.....现在电压正常了可是OP输出的声音还是有点偏小了
1
是不是NE5534不能直代AD797!!模拟部分!!
如果有问题就不会出声了!!拔掉1853,单独看看模拟部分有没有问题
OP发热解决了
现在还有1853的地14脚接上OP以后电压就从2.75V降到1.75..........1
什么是偶合变精华了出声了
可是有问题!OP我用的5534!有一组输出没声音,有一个IC很烫手,一边的声音偏小,测出1853第14脚的电压为1.75V
可是将OP全卸下以后就回到了正常的2.75V.大家帮帮忙谢谢了
还剩5套板正常出声后我再送!!!到时候说,707我昨天去买了一片!!!谢谢小野兄!!!
