REF5025: REF5025

Part Number: REF5025

I would like to know if the REF5025 noise plot in Figure 13 is the 0.1hz to 10hz noise. The spec is 3uVpp (typ.) so I suspect it might not be.

Please explain what is the noise bandwidth for this test case.

Thanks.

Hi Tony,

The graph should be 1uV/V div so it matches the 3uVpp/V EC table spec. It seems the Y axis needs the change.

Thanks for the feedback.

Reference products typically specify low frequency noise (p-p) within a 0.1Hz to 10Hz bandwidth. Can you confirm if Figure 13 is implying noise performance within 0.1Hz to 10Hz bandwidth.

Hi Tony,

Yes that is correct. Graphs like these are typically created by isolating the 0.1hz to 10hz noise and filtering out the rest of the bandwidth.
