Notes to the Characteristics
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), 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
6. Supply voltage ripple rejection is measured at the output, with a source impedance of R
