• ADL5561 OIP3 vs Pout

    In the specification section for 140Mhz OIP3 is +39dBm for AV = 15.5 dB, RL = 200 Ω, VOUT = 2 V p-p composite (2 MHz spacing), but figure 13 shows another results. Why it is so ? 

    In my point of view 2 V p-p composite (RL=200Ohm diff or not ?) = 4dBm per…

  • RE: Limitations of using AD8352 amplifier with AD9434 ADC?

    Hello Benjamin,

    I apologize for the delay in response to your original question. The AD8352 is said to have a limit of 380 MHz mainly because that is the frequency in which the harmonic distortion performance begins to degrade. I've attached a spreadsheet…

  • RE: Questions regarding AD8351: Is there a spice model?

    Jim,

    On the ADC side, you can potentially use a dual ADC to save on space and component count instead of using the AD9246 which is only a single.  You can look at the AD9258 or the AD9268 which is the 16-bit version.  Concerning the ADC driver, is there…

  • RE: high-performance ADC driver; is VGA an option?

    Actually, if you have the capability to use dual supplies, the AD8370 can be used as a dc accurate VGA. Using dual, symetric supplies, connect the VOCM pin and one of the inputs to gnd. This will set the internal bias point to 0V. I'm trying to find out…

  • RE: AD9644 - driving DC-coupled signle ended analong signal

    Hello Topi,

    Here is the paragraph in the datasheet you should be focusing on. 

    Datasheet page 13. 

    "The outputs of the AD8376 are open collectors that need to be pulled up to the positive supply with 1 μH RF chokes. The differential outputs are biased…

    Hello Michael,

    Thanks for the explanation.  I've never seen this application before and it is very interesting.  I am starting to understand your application better!  I am in the process of updating the ADL5562 input impedance on the datasheet so the…
