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
3. 20 Hz to 300 kHz (typical.
4. The ripple rejection is measured with R
5. The channel unbalance is measured with V
6. The channel unbalance at G
7. The noise output voltage (RMS value) is measured with R
