Notes
1. With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal
2. The DC output voltage with respect to ground is approximately 0.5V
3. Output voltage in mute position is measured with an input of 1 V (RMS) in a bandwidth of 20 kHz, so including noise,
