12. Dynamic characteristics
[1]
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
source
= 0
at the input.
Supply voltage ripple rejection is measured at the output, with a source impedance R
source
= 0
at the input and with a frequency range
from 20 Hz to 22 kHz (unweighted). The ripple voltage is a sine wave with a frequency f
ripple
and an amplitude of 300 mV (RMS), which
is applied to the positive supply rail.
Output voltage in mute mode (V
MODE
= 7 V) and an input voltage of 1 V (RMS) in a bandwidth from 20 Hz to 22 kHz, so including noise.
