• RE: Opamp and AD835 square-root circuit malfunction - Latches up

    Hi Steve,

    Unfortunately, your schematic has very low resolution. Please, try to remake it in high quality.

    Which the voltage range at AD835 inputs are?  In my opinion, latching of AD835 may be caused by overload of inputs.

    The output of…

     我想问一下这两个电压为什么都是+5V,不应该是一个+5V,一个-5V吗?

    hi engineer,

    i want to function ad835 as a multiplier. i want to make this component to produce BPSK Signal. i had a discussion with Mr. Neil and he suggested to visit this forum. i have applied the example of design BPSK that used AD835. i have tried…

    为什么我的AD835输出的电压不对呢??如果输入图一1VPP的正弦波信号,那么如图二所示输出只有50mv,而且全部是负压。如果输入图3只有正的1VPP正弦波,那么输出变成图四那样了图五是我的原理图,请问怎么解决?

    Hi,

    i am using AD835 for making BPSK modulator. I am using schematic amplitude modulator, whether it can produce BPSK signals? My input signal is digital. because I tried it, did not produce a BPSK signal. is there any suggestions?

    你好,我做实验时给AD835的两个X1和Y1管脚输入1V,10MHz的正弦信号,为什么输出会产生很大的变形呢?就是有直流分量,但是倍频的正弦信号却发生很大的畸变?请问这是什么原因呢?

    W = (X1– X2)(Y1–Y2)/U+ Z   请问式中的U是什么,AD835好像没有管脚U的,为什么要加Z,不明白。

    Hi musach,

    Thanks a lot for the quick reply.

    1) No, running a modified code (the one attached in my previous reply )

    2) Yes, page 2 has the AD9834 schematics(please see the attachment )
