• ltc6655 shutdown

    Hi

    What happens to the outputvoltage if the shutdown pin is activated on the ltc6655?

  • LTC6655 layout

    Let me discuss the layout.

    Q1 There is a description on page 15(datasheet)"Power and ground planes should be omitted under the voltage reference IC for best stability."

      Is there any effect on temperature hysteris depending on the presence…

  • LTC6655 .Hysteresis Plot

    Temperature hysteris is a big problem with the prototype.

    The data sheet had a distribution map from -40 ℃ to 125 ℃.(Fig11)
    Would you please give me the data from 0 ℃ to 70 ℃?

  • LTC6655 Output Gain Stage

    Hello,

    I plan to use the LTC6655 as a voltage reference for a DAC. On page 21 for the EVAL-AD5791SDZ User Guide, I see the LTC6655 being used with a non inverting op amp stage afterwards with a gain of 2. I was curious why the input into the op amp had…

  • Temperature Drift Measurement of LTC6655

    Hello,

    The LTC6655 datasheet shows smooth temperature drift curves. I ordered the EVM DC2095A-B and measured the drift by doing a temperature ramp and keeping sampling the reference output. There is some random noise shown up and it may result from my measurement…

  • Stacking LTC6655s for higher voltage references

    I need to create an extremely low noise 15V reference. I am wondering if I can use the method described in Texas Instruments app note SBAA203 to make 15V using three LTC6655s: 

    Will this work with the LTC6655? Will the noise and stability specs be maintained…

  • LTC6655 Specification of Long-Term Drift

    Hello,

    I'm DFAE. I have a question about Unit of Long-Term Drift specification. 

    The unit of Long-Term Drift is ppm/√kHr according to the datasheet of LTC6655. What's the meading of ppm/√kHr? Is it ppm/31.6hr?

    Best Regards,
