Notes
1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being
equal to the DC output offset voltage divided by RL.
2. The noise output voltage (RMS value) at f = 500 kHz is measured with RS = 0 and B = 5 kHz.
3. The ripple rejection is measured with RS = 0 and f = 100 Hz to 10 kHz. The ripple voltage VR of 200 mV
(RMS value) is applied to the positive supply rail.
4. The noise output voltage (RMS value) is measured with RS = 5 k unweighted.
5. The DC volume control can be configured in several ways. Two possible circuits are shown in Figs 14 and 15.
The circuits at the volume control pin will influence the switch-on and switch-off behaviour and the maximum voltage
gain.
