• AD8616 Supply Voltage

    Hi,

    I'm still relatively inexperienced with circuit design and I am wondering if I am misunderstanding something fundamental about this particular op amp. The AD8615 series is a single supply op amp, but one of the listed application is photodiode preamplification…

    ad8616支持±5V双电源供电吗?还是说只支持到±2.5V

  • 用AD8616做电压跟随器却有1.005的放大倍数

    我用AD8616做了一个电压跟随器,单5V供电。跟随器的输入电路由一个接地的待测电阻和一个接到3.3V精密电源的20k上拉电阻串联而成。希望通过测量待测电阻上的分压值来确定其阻值的大小。我分别接入1k10k100k1M4个精密电阻进行测试,发现每个被测电阻的跟随器输出电压都比理论计算值要高一些,大约要高1.005倍,这意味着该电压跟随器的放大倍数不是1,而是1.005。这是什么原因造成的,该如何处理,请各位老师指教。

    可以看一下AD8616 AD8618,  偏流也很小

    ADA4817-1, AD8615 , AD8616,AD8066, AD8067, 都可以参考一下

  • RE: Current noise details for AD8647

    Hi ,

    We are looking at this device for low cost TIA application and according the specification we see that other parameter matches our specs and only thing needed the current noise details .

    And we are also looking at AD8616 and AD8652

    Thanking …

    Why do you not like choppers?  We are on our fourth generation designs, and they are quite different than 15 years ago.

    If you look for rail to rail op amps, and pick ones that have Vos max greater than 40 uV, you will probably not get a chopper.
