CHARACTERISTICS
V
Notes
1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being
2. The noise output voltage (RMS value) at f = 500 kHz is measured with R
3. The ripple rejection is measured with R
4. The noise output voltage (RMS value) is measured with R
5. The DC volume control can be configured in several ways. Two possible circuits are shown in Figs 14 and 15.
