The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with a source impedance
R
Supply voltage ripple rejection is measured at the output, with a source impedance R
wave with a frequency f
Output voltage in mute mode is measured with an input voltage of 1 V (RMS) in a bandwidth of 20 kHz, so including noise.
