求解答TDA7293的使用问题！

亲爱的支持团队，


我按照数据表的建议使用TDA7293。我也在使用MUTE和STBY引脚，但不使用CLIP-DET引脚。一切都在没有任何问题。

我的问题是：

1.我可以使用1N4148二极管将TDA7293上的CLIP-DET引脚连接到MUTE引脚，使阳极连接到MUTE引脚，阴极连接CLIP-DET引脚吗？我的想法是在放大器剪辑时静音。

2.启动期间TDA7293是否对STBY引脚上的电压敏感？ STBY引脚上的电压是否有任何条件（例如OPEN），以至于在这种情况下IC可能会损坏或只是爆炸？

互联网上有一些关于TDA7293被炸毁的线索。这可能发生的具体条件是什么？

4.我可以将TDA7293用作非inv V-I转换器，使扬声器和电流检测电阻成为增益电阻吗？

提前致谢！！

温暖的问候，

拉温德拉。

Dear Support Team,


I am using the TDA7293 as per datasheet recommendations. I am also using the MUTE and STBY pins but not the CLIP-DET pin. Everything is working without any issues.  

My question is:

1. Can I connect the CLIP-DET pin on TDA7293 to the MUTE pin using a 1N4148 diode such that the anode connects to the MUTE pin and the cathode connects the CLIP-DET pin? My idea is to mute the amplifier whenever it clips.

2. Is the TDA7293 sensitive about the voltage on STBY pin during start-up? Is there any condition around the voltage on STBY pin (e.g. OPEN) such that under that condition the IC can get damaged or just blow-up?

3. There are some threads around on the internet about the TDA7293 getting blown-up. What are the specific conditions under which this can happen?

4. Can I use the TDA7293 as a non-inv V-I converter such that the loudspeaker and the current sense resistors become the gain resistors?

Thanks in advance!!

With wARM regards,

Ravindra.
