• AD8629方波输入异常

    用AD8629和FZT1047A构成V/I转换电路，输入为VH=1V，VL=0.15V，f=20kHz的方波电压，打算输出IH=200mA，IL=30mA，f=20kHz的方波电流。用PSpice搭建仿真电路如下。测试同相输入端发现在刚切换到高电平或者刚切换到低电平后有轻微振荡。把后面的三级管、电阻都去掉，将运放接成跟随同样有振荡，请问这是为什么？如何消除该振荡？

  • 关于AD8629的真假


    本人买了一批AD8629放大器，MSOP封装的，但是片子回来一看丝印和之前的不一样，是不是买到假货了？

    I bought a batch of AD8629 amplifiers, packaged in MSOP, but when I came back, I saw that the silk screen was different from the previous ones. Did I buy fakes? How can I verify?Thanks！

  • AD8629元件仅显示单个通道的5个引脚

    直接用LTSPICE从库里导入AD8629放大器，AD8629本身是双通道的，但打开的模型仅有单个通道的5个引脚。我有两路信号需要放大，从官方下载的AD8629cir文件也仅定义5个引脚，

    怎么能让它同时显示所有的8个引脚？或者说，对于双通道元件一般的做法都是画两个相同的元件吗？？？

    如下所示，打开的模型是单通道的（左），但是实际的封装应该是双通道（右）

  • AD8629S Rad-Hardness

    Good afternoon,

    I am considering the use of the AD8629S part for a future mission at Goddard, the flight datasheet lists the device tested to 10Krads.  Are there any plans to test this device further (say to 300k or so?)

  • AD8629 as a current sense

    hi 

    i want to use AD8628 as a current source .

    in it's datasheet page 19 it said that : "As long as the rate of change of the current is not too fast, an auto-zero amplifier can be used with excellent results. "
