• ad734: General usage

    Problems with AD734
    I've made the connections according to theFig.12 of Datasheet.
    OpAmp - AD8066.
    It shows 10 mv (peak-to-peak) noise with x=0, u=5v.
    When I use X=U/N (N=2, 10, 100 formed by attenuator) and U=A +triangle(f=1MHz)
    I got output…

  • AD734: power consumption calculation

    Could you please let me know the power consumption of the AD734.
    I can only find the quiescent current and the operating supply range on page2
    of the datasheet and the internal power dissipation on page3.
    Could you give me the range of…
  • About the output of the AD734

    Hi
    I have a question about the Transfer function of the AD734.

    I have created the circuit shown in Figure 24 of the datasheet in LTspice and ran a simulation.
    One of the results is shown in the attached image.

    One of the results is as follows.

    X1-X2 = 100mVp…

  • AD734 U input voltage range

    Hello,

    I designed and fabricated a PCB that includes the multiplier chip AD734.

    Please find attached the Altium schematic of the AD734 chip in pdf.

    In the configuration I used, the output of the multiplier (W) is given by the following equation:

    W = (U…

    Original Question: Encrypted SPICE AD797 and AD734 by dhhsieh

    Can someone please give me encrypted ADIsimPE files for the AD797 low noise op amp and the AD734 analog multiplier?

    I have hit the 'too many nodes' limit. 

    Sincerely

  • Heating issue of AD734

    I am using AD734 as a RMS-to-DC Converter(Page no 16 of datasheet).
    My circuit is same as that of given in datasheet. But IC is getting heated to 72 celsius (or 161 F) when I am giving 1 to 100 Hz sinewave sweep (T=20 sec) periodically at input.
    Is it…

  • 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…
