Do you have a diagram of the noise of the LTC6655LN measured under the same conditions as the LTC6655?

Category: Datasheet/Specs
Product Number: LTC6655

Hello.

I have a question.


The following figure is the noise figure for the LTC6655 from the datasheet.

Do you have a diagram of LTC6655LN measured under the same conditions as this one?

Best regards,

  • The datasheet doesn't have a diagram for the LTC6655LN but it does provide output voltage noise specs in the electrical characteristics table.

    The LTC6655-2.5 has a typical 0.1Hz to 10Hz output voltage noise of 0.25 ppmp-p (625nVp-p). This can be viewed in the diagram you've included.

    The LTC6655LN-2.5 has a typical 0.1Hz to 10Hz output voltage noise of 0.12 ppmp-p (300nVp-p) when CNR = 100uF. This is approximately half of the peak-to-peak noise when compared to the LTC6655-2.5.

  • The core of both products is the same, the NR capacitor rolls off noise based on an internal impedance.
