• AD834 &AD835

    The AD834 and AD835 are very expensive these days, £35 in small quantities from distributors. They used to be a small fraction of this price. What's going on?

  • ad834 rev. F

    Hello,

    Figure 23. Wideband Three-Signal Multiplier/Divider is incorrect in Rev. F of the datasheet: The Y2 input of the lower ad834 is incorrectly left floating.

  • AD834 Evaluation Board

    Hi

    We are planning to implement AD834 multiplier in our board. Is there any evaluation board for this part?

    Regards

  • Mean-squared detector on AD834. Scheme figure 3 an-212.

    When tested at a temperature below 0 C, the signal dropped sharply to -30...-50 mV(0.7 mV under normal conditions). Removed the capacitors standing in the integrator. Soldered the feeder through the capacitance and resistance to the output. Detected oscillation…

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

    Hello Akira,

    Apologies for the delay.  The AD734 has the lowest total error over temperature of the 3 parts.  The AD835 could also be considered.  AD539 is a 2 quadrant multiplier, whereas AD834, AD734, and AD835 are 4 quadrant.  They all have different signal…

  • AD834 input common mode voltage?

    On the Data Sheets I found the "Full-Scale Range" (+- 1V) and the "Clipping Level" (+- 1.3V), but nothing about the input common mode voltage (with +-5V power supplies).

  • 有关乘法器AD834的问题

    我按着手册上的图(图一)做了一个电路图,原理图是如图二,巴伦用的是TC1-1-13的型号,出现了个问题。

    1、X,Y的输入都是1V的正弦波信号,输入频率也是一样的,相当于倍频把,但是当我输入频率增加的时候,-3dB带宽连100MHz都达不到,是我电路的问题吗?

    2、手册上写的带宽能到500MHz才对,还是说500MHz的不是用图一的电路图,应该用图三?这两个图有什么区别吗?区别是什么?变压器带抽头和不带抽头有差吗?CT端接电源又是为什么呢?如果用图三的电路应该选择什么型号的变压器可以呢?
