• ltc6655 shutdown

    Hi

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

  • 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…

  • RE: LTC6655 layout

    Hi Yuji,

    A1    Yes. The reason why omitting the power/ground planes below the area of the IC is because of the mechanical stress cause by it when temperature changes. Different material have different Coefficient of Thermal Expansion. The material of the…

  • 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,
