REF6133: REF6133 - interpreting noise data

Part Number: REF6133

Hi Team,

my customer is asking following questions about REF6133 noise data:

- Low Integrated Noise is listed as uVpp/V. Usually it is given as uVpp only or nV/Sqrt(Hz)

- for comparison, at REF3133 the 1/f noise is listed as uVpp

Can you please clarify/confirm?

Thanks!

Regards

Andreas

  • Hi Andreas,

    1/f noise scales with output voltage. The 3uVpp/V 1/f noise spec will scale with the output voltage of the REF6133. So 3.3V * 3uVpp/V = 9.9uVpp
    On the REF3133, the noise is already given to the appropriate scaled output voltage.
