Notes
1.
Gain of the amplifier is
in test circuit of Fig.3.
2.
The noise output voltage is measured at the output in a frequency range from 20 Hz to 20 kHz (unweighted), with a
source impedance of R
S
= 0
at the input.
Supply voltage ripple rejection is measured at the output, with a source impedance of R
S
= 0
at the input.
The ripple voltage is a sine wave with a frequency of 1 kHz and an amplitude of 100 mV (RMS), which is applied to
the positive supply rail.
Supply voltage ripple rejection is measured at the output, with a source impedance of R
S
= 0
at the input.
The ripple voltage is a sine wave with a frequency between 100 Hz and 20 kHz and an amplitude of 100 mV (RMS),
which is applied to the positive supply rail.
Output voltage in mute position is measured with a 1 V (RMS) input voltage in a bandwidth of 20 kHz, so including
noise.
