12. Dynamic characteristics
[1]
The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with a source impedance
Rsource =0 at the input.
[2]
Supply voltage ripple rejection is measured at the output, with a source impedance Rsource =0 at the input. The ripple voltage is a sine
wave with a frequency fripple and an amplitude of 700 mV (RMS), which is applied to the positive supply rail.
[3]
Output voltage in mute mode is measured with VGC = 0 V and an input voltage of 1 V (RMS) in a bandwidth of 20 kHz, thus including
noise.
