請問是不我問題太簡單了嗎

LM393適合于作純比較器.
LM358適合于作運放.
Refer to LM358 and LM393 datasheet.

這個問題等價于比較器和運放有什么區別.
比較器速度快,運放線性度好.

頂!
謝謝!!!

那LF353和這兩有何區別?能做比較器嗎?有什么優點?

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輸入范圍不能到負電源的,358和393都可以.
另外,358、353是推挽輸出,339是開路輸出要上拉電阻.
