• AD633: input coupling

    I have connected AD9850 and AD633 like in the attached diagram. AD9850 outputs
    0-1000mV sine wave, and a 0.1uF capacitor is placed between AD9850 and AD633.
    The AD633 is powered by +-5V, and the 2nd pin is connected to GND. I found:

  • RE: Problems of using spice model for simulation AD633.cir (LTspice)

    Hi,

    The SPICE models of ADI are optimized to be used in NI Multisim ADI Edition. Fortunately, I was able to talk to one of my colleagues who is familiar with LTspice. The AD633.cir is to be renamed to AD633.mod to be able to create a AD633.asy file.…

  • RE: AD633 AD534 square root connection -- linearizer RF detector response

    Hi,

    Based on the transfer function of AD633, I think it shouldn't be a problem. As you can see on the block diagram, the input side of AD633 will only get the difference of X1 and X2 then multiply with the difference of Y1 and Y2.

    Regards,

    Phi…

  • RE: AD633  MULTIPLIER

    OKAY CAN YOU SEND ME A HAND DRAWING OF THE AD633 WITH ONE OF THE INPUTS HAVING THE INPUT SIGNAL WE WILL CALL IT THE REF . SIGNAL OF THE SINEWAVE AND SHOW ME THE OTHER INPUT TO THE AD633 AT WHAT VOLTAGE SHOULD IT BE SO THAT WHEN THE SIGNAL IS CONNECTED…

  • RE: Evaluation board for AD538

    Hello,

    The only multiplier (divider) product that has a released eval board is the AD633 (look for the AD633-EVALZ), it is set up for division.

    If you consider the difference in package leads (8-leads vs. 18)  you're just as well off using a hunk of vector…

  • RE: AD633 error on LTSPICE

    I have had problems with the AD633 model. The developers for my simulation environment Simetrix have offered me a corrected model which I was told disables the common mode model in the AD633, which is allegedly faulty and causes the analysis to head off…

  • AD633-EVALZ

    The AD633-EVALZ was tested for division.

    The same voltage signal was applied to the denominator and the numerator using a function generator.

    The denominator and the numerator are 1V sin signal and offset volatage is 1V, frequency is 80Hz.

    Negative supply…

  • RE: What is an evaluation board and how do I use it

    Hello,

    Thank you for the question regarding the AD633 eval board.

    I was the designer of the board. The AD633 was designed before ADI made it a practice to design eval boards for their products, now there are thousands of boards for various products…

  • AD633 Input Offset Problem

    Simple AD633 circuit.

    1. As AM Modulator per data sheet

    2. Signal into Y1 is 1000Hz sine at 2V p-p (via 10uF cap)

    3. Signal into Z is connected to Y1

    4. Signal into X1 100Hz sine at 8V p-p (via 10UuF cap)

    5. Y2 and X2 are grounded

    6. Supply voltage…
