100台TDA7297只工作了2台

嗨Salazar，
 
 当ST仍被命名为SGS-Thomson时，TDA7297是非常成熟的AB类设备。
 根据您的描述，如果您的应用电路（原理图和PCB布局）在过去已经通过TDA7297进行了验证，那么您应该得到一些非ST原装的器件。
 
 澄清一下，最好与您的经销商联系。
 
 谢谢

Hi Salazar,

TDA7297 was very mature class AB device when ST was still named as SGS-Thomson.
according to your description , if your application circuitry (both of schematic and PCB layout)  had been proven with TDA7297 in the past , you should get some device that was not ST original .

to clarify it , it's better to contact with your dealer.

thanks

是的陶先生，我想是的，这台设备并非原创。我在ALIEXPRESS购买。这些TDA7297我在ALIEXPRESS购买它们，我认为它是严肃的卖家，但事实证明不是原始的。如果另外一个设备可以替代pin到pin？或者你可以建议另一个类似的放大器，或者你知道我在哪里买原装TDA7297知道吗？陶先生，谢谢你。

Yes Mr Tao, I think so, this device was not original. I bought in ALIEXPRESS.  These TDA7297 I buy them in ALIEXPRESS, I thought it was serious sellers, but proved not original.Sabe you if another device that can replace pin to pin? or you can advise another similar amplifier, or Do you know where I can buy the original TDA7297 know? Thank you, Mr. Tao.
