Hi,
My customers are considering AD 8602.
So I got a question.
Is a protective diode etc. in the Input & output stage of the AD8602?
If voltage is applied to Input when power supply is not being applied to the AD8602,
I am concerned about whether the…
Hi,
My customers are considering using the AD8602.
So I got a question.
They applied 2.0 V to the differential input pin and kept operating at 75 ° C for a long time.

Connect a 6.8 kΩ resistor to GND and operate…
以下是一个微小电容的测量电路,为了减小连接电容和电容测量电路的线缆引入的电容,采用了驱动电缆技术。其中用到了AD8602芯片,但没有给出具体连接图。哪位高手能给出一个连接图,另外放大器的性能对减小电缆电容很关键,能否推荐一个更好的AD芯片?
上图中所描绘的元器件RL、CL、RG、CG都是带有电容电阻的长导线电缆的等效示意图,只需要一个运算放大器OP作为射极跟随器就够了。作为射极跟随器(v=1,放大倍数为1)的运算放大器,OP将导线电缆的内外电势保持一致,消除了信号电缆间的容抗,使信号导线与内屏蔽导线之间的电缆电容不起作用…
Hello Kchan770,
There are no PCNs for AD8602 that documents a lead frame change.
I would recommend that you go back to your point of purchase to verify any concerns.
Thanks,
