Part Number: LM61480


Tool/software:

Hi Team,

Could you please provide the noise rate specifications for LM61480RPHR, LM61495RPHR, and REF7040QFKHT? This info is needed for our design review.

Regards,

Arshad

    Hi Arshad,


    Please find the noise rate specifications for the requested parts below:


    • LM61480RPHR / LM61495RPHR: As these are buck DC-DC converters, standard “noise rate” specifications such as voltage noise density (expressed in nV/√Hz) are typically not provided. However, the datasheets and technical documentation focus on EMI performance, output ripple, and switching noise characteristics, which determine overall noise. No explicit voltage noise spectral density value is specified in the datasheets for these models.


    • REF7040QFKHT:
    • 1/f Noise (0.1 Hz to 10 Hz): 0.23 ppm p-p
    • 10 Hz to 1 kHz: 0.35 ppm rms

    Thanks and Regards

    Naresh
