高端电流检测芯片区别

Other Parts Discussed in Thread: INA200, INA282, INA117

采用差动放大器INA117和采用专门的高端电流检测芯片,比如INA282,INA200有什么区别,后者有什么优势?是不是在INA117差放后加一级相应倍数的放大,效果就跟采用INA282,INA200等差不多。

谢谢~

  •    INA117,INA282和INA200都具有宽的共模范围,但INA117是单位增益的差分放大器,INA282和INA200具有较大的增益,而且还集成了比较器,相比之更适合做高位电流检测。你所说的INA117后面再加一级放大器与INA282和INA200的效果是相似的,但这样电路在集成度和电路复杂度上是没有优势的。
