Electrical characteristic curves
The graphs shown in this section use the following abbreviations:
● RL+ 15 µH or 30 µH = pure resistor + very low series resistance inductor
● Filter = LC output filter (1 µF+ 30 µH for 4 Ω and 0.5 µF+15 µH for 8 Ω)
All measurements are done with CS1 = 1 µF and CS2 = 100 nF (Figure 2), except for the
PSRR where CS1 is removed (Figure 3).
