• LTC6409 DC-Coupling

    Hello

    In the Simulation-Demo (LT-Spice) and in this Thread the LTC6409's single ended input is DC-coupled.
    Will this circuit work with Devices which have a non biased output voltage (Vcom=0V, no DC-offset)?
    I want to connect the IFout from a passive…

  • LTC6409 resistor calculation

    Hello

    I have a circuit as shown below: (configured as a differential amplifier)

    now I have a single ended source and I  want to apply it to the first input port. can I use a 50 Ohm terminator instead of second source?

    Thanks

  • Choosing a bypass capacitors for LTC6409

    Hello,

    Our customer is designing an RF application with using differential amplifier LTC6409 for driving ADC.

    Together with this amplifier they use feedback capacitors Cf in the parallel with feedback resistor.

    In the datasheet it is mentioned that a…

  • ibis model for LTC6409 input

    Hi,

    I know an ibis model does not exist for this device LTC6409. What is your recommendation to model the input of the LTC6409 while checking for SI issues on a board?

    Thanks,

    Uttara

  • Spice models or S-Parameters for LTC6409 and LTC2208

    Hi EZ team,

    My customer is using LTC6409 for driving LTC2208 and need to simulate between these devices including the PCB trace with Keysight ADS. I have tried to find out the Spice models or S-Parameters in ADI web site but can't find out them.

  • ADC driver for AD9694

    Dear experts,

    We are looking for a single ended to differential amplifier to drive AD9694. We searched and found

    LTC6409. We'd like to have DC-coupled.  For the anti-aliasing filter, can we still use the recommended

    circuit on AD9694 datasheet which…

  • Improving Linearity by Using Absorptive Filters

    When driving a direct sampling high speed ADC, the most likely place to degrade the performance is the interface between the final amplifier and the ADC.  With any direct sampling ADC there will be nonlinear charge produced in the sampling process. This…

  • LTC5585 output bias resistor value

    Hello,

    I am designing an I/Q Zero IF downconverter using an LTC5585 and amplifier LTC6409 to drive an A/D. The datasheet of the Mixer LTC5585 says  that an output pull-up resistor should be included to guarantee a DC bias voltage of Vcc-1.5V, in my case…

  • RE: anti aliasing filter for an ADC

    The AD9248 has a common mode voltage that is 3.3V/2 = 1.65, the LTC6409 can easily provide that and do a gain of 10 and do a single ended to differential conversion.  

     

    The filter you have picked out from mini circuits should be ok, but only before the…

  • DC2266A 16-Bit, 210Msps ADC FMC reference design and Linux drivers.

    Hi,

    Has anyone modified any of the ADI reference designs or created the Linux drivers for the DC2266A?

    LTC2107 and LTC6409.

    ZC706, ZCU102, KC705, KC102, Arria 10 SoC, Arria 10 GX or Zed.

    Thanks in advance.
