  • TIDA-00684: Use of CPLD

    Resolved
    Part Number: TIDA-00684 Hello team, In TIDA-00684 reference design, the schematic http://www.ti.com/lit/df/tidrov6/tidrov6.pdf calls for the use of CPLD, is that essential for the DAC38J84 JESD204B communication or can the DAC be communicated with directly…

  • RE: DAC37J82: DAC37J82

    Resolved
    Hi Tamir, The reason I suggested using a fully differential amplifier is because they have a VOCM pin that allows you set the common mode of the output signal. For a suggested circuit I would recommend you look at the High-Bandwidth Arbitrary Waveform…

  • RE: LM7171: Circuit Board Material vs Rise Time, Stability,Etc.(FR1 vs. FR4) and LT1166 Stability For Function Generator Output

    Resolved
    Hello Fred, I was looking into other products; it does seem like the LM7171 is the only one that fits all your specifications you have listed. If you would be able to go with another package other than the DIP option; there are about 60 devices that…

  • RE: THS3217: Interface design with current-sinking DAC3283

    The THS3217/3215 were designed to simplify the DAC to amplifier interface. I wrote the datasheets, but apparently not clear enough The buffers can handle quite a range of input common mode and generate only the differental output in the D2S output (rejecting…

  • RE: LMH6702: Interfacing LMH6702 with DAC5681Z

    Resolved
    Hello Seema, Yes, if you have an AC coupled requirement a balun is best with your DC offset brought into the centertap on the secondary. If you need DC coupled output, LMH6702 is a good solution. I would note that for best HD suppression, you need to…

  • RE: THS3217: Changing Resistor Values

    Resolved
    Hello Elisha, The interstage network is intended to be pretty flexible including the idea of adding image reject filters right there. Often the high speed dacs are specified with a 50ohm at their outputs to ground (for current sourcing DACs) and the…
