    Original Question: AD633 using ADIsimPE by crlMIDI

    I tried to simulate the voltage-controlled quadrature oscillator of the AD633 application note, using ADIsimPE, but it said there are too many analog nodes. I note that the model for this fairly old part…

    Original Question: AD633 noise SImetrix model doesn't match datasheet by dhhsieh

    Hi everyone, I am trying to do a noise simulation of a circuit using the AD633 low-cost analog multiplier. As a first check on my results, I have wired the multiplier…

  • 关于AD633的使用疑问

    目前我们想将超声波信号转换成人耳能听到的声音，想用AD633作为混频器使用，目前我们超声信号的频率为40Khz左右，另外想用有源晶振产生32.768Khz的信号，这样两个信号输入到AD633,在通过一个截止频率为10kz的低通滤波器滤出两个信号的差频信号，然后在通过一个音频放大器驱动耳机，不知道这样是否可行，如果可行在使用的时候有没有什么需要特别注意的地方。另个个人感觉这个方案的成本有点高，不知道除了这个方法还有没有什么更好的方案，谢谢了。。。。。。

  • AD633除法电路

    使用AD633与AD711按照官方提供的电路搭建了一个除法器，在使用中发现与实际不符，求解答

    一.

        这是输入的两个信号，最上面一个作为被除信号，下面一个作为除信号。

        这是通过除法器后的信号，其中最上一个信号是被除信号，下一个为除法器输出信号（结果），我认为在被除信号处于正半周的时候，输出结果没有什么问题（不考虑过零点），但是在负半周的时候，我认为应该是一个接近于3V的直线（取被除信号负半周峰值为0.4V,除数信号负半周峰值为1.2V）,结果

    与我预期的不符合，求高手解惑。

  • 关于AD633的仿真

    最近在用AD633做仿真电路图如下所示

    输入为1k和5k的信号，参考回路为1k信号，有效值为1V，后面带通滤波器中心频率1k，低通截止频率为100Hz。但是输出为什么是10Hz的信号，如下图所示
