The noise output voltage is measured at the output in a frequency range from 20 Hz to 22 kHz (unweighted), with a source impedance
R
Supply voltage ripple rejection is measured at the output, with a source impedance R
from 20 Hz to 22 kHz (unweighted). The ripple voltage is a sine wave with a frequency f
is applied to the positive supply rail.
