• AD620和AD8037级联

    大家好,我使用AD620做前置放大器,后面使用AD8037继续放大,两个运放电路单独测试效果很好,但是连接之后要不然是一直输出一个正弦信号,要不然就是一直输出一个负的直流电压,AD8037使用的是手册上的放大电路,AD620输出端直接连在图中IN,请问这是什么原因

  • AD8037供电电压不对称

    有个问题需要请教一下,使用+3.3V和-5V给AD8037供电,会有什么影响?

  • AD8037整流的同时能否钳位

    ad8037做整流使用时,能否同时应用钳位功能,如下图,能否在VH端加电压起到钳位作用?

  • AD8037放大倍数达不到设计值

    使用AD8037的时候,按照手册上的电路和数值设计了放大倍数为2的电路,并且VH端接1.5V,VL端接地,用于输出箝位,但是在调试的时候发现一个问题,实际放大倍数一直是1,但是钳位电压依然是3V,而且芯片的温度稍微高一点,很纳闷,不知道是什么原因,请指教

    Hi,

    The direct replacement for OPA699 is AD8037.

    Hello there brantchen,

    Good catch:

    U6, U7: AD8036

    U8: AD8037

    We will be including this info in the next document update.   -Bruce H.

  • RE: Looking for OPA with voltage limiting function

    Hi Marc,

    I think you might be looking for the AD8036/AD8037.

    We're always interested in improving our product search tools.  Can you advise what you tried?  Did you do a keyword search or were you using the parametric search tables?

  • RE: AD8036: need clarification on "fast rectifier" use.

    Hi Ilya,

    Sorry for the delayed response.

         1. First, the datasheet theory of operation (pg. 15, paragraph 2) says that AD8036 and AD8037 can be used in either inverting or non inverting configuration but the clamp in function will only work at non inverting…

  • RE: 问题: AD620前置放大电路图

    你好,我也是使用AD620做前置放大,后面连接的是AD8037,两个运放单独测试效果很好,但是连接之后输出-5V直流电压,请问这是什么原因,谢谢

  • RE: Is there an Op Amp that can clamp the output at  5V (unipolar operation)?

    Hi Ted,

     

    According to one of our colleagues, AD8036 and AD8037 are the only clamping amplifiers that Analog Devices have.

    AD8036 operates at +1 gain while AD8037 operates at +2 gain.

    AD8036 is guaranteed to operate on maximum of +/-6V of supply voltage…
