版主TDA9109和TDA9109/S能互换吗？-电脑-数据之家

请问TDA9109和TDA9109/S能互换吗？
---------------------------------
TDA9109和TDA9109/S能互换吗？不能互换，内电路有异。

---------------------------------
TDA9109和TDA9109/S能互换吗？具体的您可登＜２１ＩＣ中国电子网＞查ＴＤＡ９１０９Ｓ和ＴＤＡ９１０９，本来我想发附件给您，但没有办法发ＳＯＲＲＹ
---------------------------------
看样子，是一样。。。9109S我换了9109后。。行幅偏右，不能调整
---------------------------------
3楼提供的资料不太准确：TDA9109与TDA9109S的区别在于9脚，前者是HFOCUSCAP(即水平动态聚焦振荡器外接电容)，后才是HMOIRE(即莫尔纹校正输出)。但在实际应用中，TDA9109S的9脚多为置空不用，而TDA9109的9脚通常外接CAP电容，所以，如果机器原来是使用水平动态聚焦功能的或莫尔纹校正功能的，两者就不能直接代换，除非关闭各自的功能。这需要调整总线数据。
---------------------------------
不能代换。代上能显示。但有行的问题。
---------------------------------
不能换我试过行幅偏右,行中心不可调!
---------------------------------
从两者的PDF看，应该可以代换，但要修改外围元件参数或存储器相应的数据。如果没有把握，直接用TDA9109S代吧，我们都有。
