Notes to the Characteristics
1.
With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal
to the DC output offset voltage divided by R
L
.
2.
The DC output voltage with respect to ground is approximately 0.5V
P
.
3.
Output voltage in mute position is measured with an input of 1 V (RMS), including noise, in a bandwidth of 20 kHz.
4.
Total gain setting at +20 dB.
5.
The noise output voltage is measured at the output in a frequency band from 20 Hz to 20 kHz (unweighted), input
source impedance R
source
= 0
.
6.
Supply voltage ripple rejection is measured at the output, with a source impedance of R
source
= 0
at the input.
The ripple voltage is a sine wave with frequency of 1 kHz and an amplitude of 100 mV (RMS) is applied to the positive
supply rail.

The rise time (t
r
) and the width of the pulse (t
