• AD633  MULTIPLIER

    HELLO IAM WORKING WITH THE AD633 MULTIPLIER AS A FEEDBACK LOOP CONTROL THAT WILL CONTROL THE AMPLTD OF A SINEWAVE

    FROM EACH POWER MODULES

    EACH POWER MODULE WILL OUTPUT 115 VAC AND THE FEEDBACK SIGNAL WILL BE FROM A SMALL SENSE TRANSFORMER OF SOME LEVEL…

  • 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:
    1…
  • AD633: Asymmetric supplies

    I would like to know whether it is possible to use a AD633 analog multiplier
    with unbalanced supplies eg +24v,-5v or +12v,-5v

    Alternatively can you recommend a way to calculate a square of a voltage in a
    single supply circuit or one…
  • AD633 , higher orders ?

    Hi all, I wanted to use either dy/dx or the double angle formula to add overtones to an audio signal ( specifically with advancing the slew rate in a manner proportional to frequency, not limited by an RC constant).  The AD633 looks great, and even will…

  • 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…

  • AD633 Control voltage polarity

    Hi Hopefully this is an appropriate place for the following question. Apologies if not.

         I hope someone can help me find a smarter way to resolve a small problem. I've been using the AD633 as a voltage controlled low pass filter. The problem is that…

  • AD633 using ADIsimPE

    Original Question: AD633 using ADIsimPE by crlMIDI

    I tried to simulate the voltage-controlled quadrature oscillator of the AD633 application note, using ADIsimPE, but it said there are too many analog nodes. I note that the model for this fairly old part…

  • AD633 offset and supply

    Hello,

    I need some help with my circuit. 2 sine waves are generated with 2 AD9833's, then are amplifier and filtered with 2 1st order low pass filters, and then connected to the AD633. As the sine wave have about 200 mV offset, I'm using 2 coupling capacitors…

  • AD633 Vos drift over temperature

    What is the figure for the offset voltage drift of AD633?
    We have found such parameter shown in AD632 as below.
    Would you kindly offer this parameter to us if it is convenient.

     

    We performed some temperature measurements to determine the…
  • 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…
