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 RL.
2. The DC output voltage with respect to ground is approximately 0.5VP.
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 Rsource =0 Ω.
6. Supply voltage ripple rejection is measured at the output, with a source impedance of Rsource =0 Ω 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 (tr) and the width of the pulse (tw) are not critical.
