FIGURE 1 – Noise Density Measurement Circuit
Noise density, (ND) is specified in microvolt-rms per
square-root-hertz. Actual measurement is performed
using a 1 kHz to 3 kHz frequency bandpass filter at a
constant Zener test current (IZT ) at 25 oC ambient
temperature. ND is calculated from the formula.
