• Can two AD8337 be cascaded?

    Hi,

    In my current design,I need to cascade two AD8337,and here's the schematic.

    AD8337

    But it seems to work abnormal.

    1.The Vgain of AD8337 will oscillate if I put a 1nF capacitor(C7 and C8) in pin 7,and it will destroy the VOUT.When I remove the capacitor…

  • AD8337 Spice model on webpage is old Rev A model.

    The spice model file that is linked on AD8337 web page has many errors and is
    REV.A from 2011 although your website labels the file  as REV.B from 2012.
    Could you please send me the correct spice file please or replace the linked
    file…
  • AD8337 preamp gain of -0.5

    Hi,

    I am planning to use the AD8337 in inverting gain configuration with a preamp gain of -1/2 (Figure 67 in the datasheet, Rfb1=200, Rfb2=100) resulting in a total gain range from -12 to 12dB.
    Since my input signal will be a multi sine signal with frequencies…

  • About the internal block of the AD8337 (Is a capacitor included?)

    Hi,

    I would like to use AD8337.

    So, I have a question. Please help me.

    Question:

    I am experimenting with VGA (Variable-Gain Amplifier).

    When I was considering using ICs made by other companies,
    A problem has occurred (the contents cannot be disclosed…

  • AD8337 supply

    I'm trying to simulate on LTSPICE an AGC loop made by components whose supply is 3.3V max. After discovered here that my original choice for VGA, AD8330, has convergence problems on LTSPICE, I found interesting for me the AD8337 component, whose supply…

  • AD8337 Simulation

    I tried to simulate AD8337 with it's model provided in ADI website. But in the Orcad 16.6 PSpice,I get error ERROR(ORPSIM-16366): Line too long. Limit is 132 characters.

    How can I run the simulation smoothly?

  • AD8337 package and footprint

    Good afternoon,

    I'm looking for the package and footprint of the AD8337 VGA to be used in Altium Designer. At this moment, I'm not able to find any library that contains this component. Is there any way to obtain this?

    Thank you very much
