• AD539

    AD539

    Hi

    I would like to build a very good programmable gain amplifier going from 10kHz to 10MHz with minimum phaseshift and minimum gain-error. I think the AD539 is a good candidate - but what is its error? According to Analog Devices selectiontable…

  • AD539 Unused Channel?


    Hi,

    I am using the AD539 in my desing, but I only need to use one of the two channels.

    How do I terminate the unused channel on inputs and outputs.

    Thanks;

  • AD539  spice model needed

    Hi

    i immediately need spice model for AD539

    1.can Analog help in providing one, ? or if it is not

    2. or if it is not avialable , is there any alternate multiplier IC which can do the same job with same bandwidth

    3. or even if alterative is not available…

  • Temperature dependence of gain performance about AD834, AD734 and AD539

    Hello Support-team,

    I'm DFAE in Japan. I have received a question about a temperature dependence of gain performance of AD834. The customer evaluated AD834 and he satisfied the linearity. But the temperature dependence of gain was not enough for him.…

  • 关于二象限乘法器AD539的一些疑问

    各位,请教乘法器的一些问题:

    1.二象限乘法器AD539中控制通道Vx只能输入正信号,但是否只能为直流电平(用做电压控制放大器)?

    2.如果控制通道Vx输入交流信号,理论上是否应该做偏置,使之在零电平以上?这样做是否会影响输出结果?这样是不是这种芯片的常规用法?

    3.二象限乘法器能否作为两路交流信号混频使用?具体怎么用?

    PS:我混频的两路信号均为正弦信号,频率为(2MHz~1.996MHz)/(400kHz~396kHz).

    拜谢!

  • AD539没有spice模型,该如何仿真,Multisim里也没有此仿真器件

    最近需要用到AD539乘法器,由于Multisim里面没有该仿真器件,在ADI官网上找AD539的spice模型也没有找到,无法仿真。根据数据手册上的电路图在面包板上进行测试,输入1mv,1KHZ的正弦波,VX增益用的是1V的直流电,但输出端Vw处始终没有波形,检查不出原因,谁能指导一下,或者告诉我可以在哪个软件上仿真,或者给我一个AD539的spice模型文件,谢谢了。根据下面这个电路图连接的电路。

    Hi Monse,

    I was looking on some of our multipliers/dividers product and found a few devices that can cater your supply rails requirements. AD834, AD835,  AD538 and AD539 however, there are no exact configuration on how to achieve your transfer function…
