• RE: AD645电流转电压运放

    可以使用AD8067  ADA4817-1

  • RE: 求运放推荐

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

  • AD8067 Spice Model Problem

    I am trying to run the AD8067 Spice model in a third party simulator. I have tried inverting and non-inverting configurations with a gain of 10. What I see is large currents between +Vs and the non-inverting input and gain far less than 1. I have no problem…

  • using AD8067 as inverting amplifier

    Hi,

    I tried to work with AD8067 operational amplifier as inverting amplifier. My input resistance is 12k ohm and feedback resistance is 10k ohm. Now gain should be less than one. I tried to simulate it in LTspice with spice model of AD8067 from analog…

  • RE: AD8421 output offset of -400mV

    Aditya,

      The AD8067 is only stable at a gain greater than 8.

    Try the AD8065.  Also, the abs max is 24V, so it is dangerous to run on +/-12V.

  • RE: Re Current drive capability of Wavegen tool in Analog Discovery

    HI:

    The final output driver for the AWG channels is the AD8067 amplifier configured in

    the inverting mode with an 11 K feedback resistor and a 1 K input resistor.

    Rather than try to just answer your question for one set of conditions please refer

  • AD8067使用问题,总是自激,求助。

    AD8067使用问题,总是自激,求助。

    仿真没问题,实际测试中也可以看见相应的放大倍数。但是不管怎么弄,还是自激,有50-70MHz的信号。反馈回路加了小电容没用,输入并上电容也没用,求助大神。实现是解决不了。。地我也特地刮了,增加了地的接触面积。

  • 光电二极管前置放大电路 AD8067

    我要对一个脉冲宽度为5ns的激光脉冲信号放大,探测器是PIN光电二极管,通过计算后得到光照时光电二极管的输出电流时0.2mA左右,所以我准备使用前置放大电路,选用的是OPA657现在有些问题:
    1.我现在有两个思路,因为放大电路输出后接峰值保持电路和比较电路,所以我放大后的信号只要在1V左右就可以了,根据前置放大电路的原理,输出电压是二级管电流和Rf的乘积,方案一:那么我如果选用K级以上的电阻的话,前置放大电路就可以直接接峰值保持电路,但是考虑到5ns的信号,Rf过大电阻的电容效应是否会影响放大的特性…

  • ADA4896 micro spice model for LTSPICE use

    Hi

    The ADA4896.CIR doesn't work for LTSPICE. The BF value is a big negative value.

    Could you post an alternative spice model working for LTSPICE? Any format is ok.

    by the way, the AD8067 model doesn't converge in MultiSim. I have to use it in…
