• AD8676 Unity Gain Stability

    Hi team,

    I have a question about the unity gain stability of AD8676. I am not sure if the AD8676 can be used for unity gain configuration. I am currently using it in a configuration similar to the circuit below.

  • AD8676 supply voltage

    Dear Sir,

         Just notice that the datasheet only specifies bipolar supply voltage for AD8676.

         What if we use uni-polar supply for AD8676? Will there be any abnormal  phenomena?

         Or would you kindly suggest some additional circuity for our application…

  • AD8676 popcorn noise

    Hello,

    I have some questions about the AD8675 (or 8676) and its popcorn noise.

    I plan to use an AD8676 (or AD8675) in order to measure [0,1Hz;10Hz] noise of a low noise voltage source. I have chosen this amplifier as, according to the datasheet, it has…

  • AD8676芯片的差分电压

    通过看数据手册后发现：手册中提示差分电压为+/-0.7V，

    这个指的是两个输入端的电压差不能大于0.7V吗？

  • 关于AD8676输入阻抗

    大家好！

            考虑到AD8676的失调电压等指标较优，目前正采用该运放对传感器的输出电压进行处理。由于所购国产传感器的内阻较大（K级别），所以比较关心运放的输入阻抗。

            细看AD8676的datasheet后，只留意到输出阻抗的说明。

            不知哪位大侠对其输入阻抗有所了解。如果有所了解，麻烦介绍一下。谢谢！

  • ad8676对5V电压基准放大至10V多次烧毁

    我按照UG-184（AD5781DAC参考电路）搭建了反比例放大电路，实现对5V电压基准放大至-10V，在PCB板上芯片内一运放电路实现电压跟随阻抗匹配功能工作正常输出5V，另一个运放出现烧毁输出13V之多，第二块在PCB板上出现了烧毁，第三块使用面包板进行测试也出现烧毁，且导致线性电源的CH4（提供5V模拟基准电压）毁坏。电源供电采用线性电源正负15V供电，电源CH2的+与电源GND相连并且也是运放的地，CH2的-作为-15V；CH1的正作为+15V，-与运放地、电源地GND、CH2正连通；CH3…
