LM358和393在应用中有什么不一样啊?

请问是不我问题太简单了吗

LM393适合于作纯比较器.
LM358适合于作运放.
Refer to LM358 and LM393 datasheet.

这个问题等价于比较器和运放有什么区别.
比较器速度快,运放线性度好.

顶!
谢谢!!!

那LF353和这两有何区别?能做比较器吗?有什么优点?

1.Features
• Internally trimmed offset voltage
• Low input bias current
• Wide gain bandwidth
• High slew rate
2.The LF353 is pin compatible with the standard LM1558 allowing
designers to immediately upgrade the overall performance of
existing LM1558 and LM358 designs.
3.Refer to LF353 datasheet

353输入范围不能到负电源的,358和393都可以.
另外,358、353是推挽输出,339是开路输出要上拉电阻.
