Electrical characteristics curves
The graphs shown in this section use the following abbreviations:
● RL + 15μH or 30μH = pure resistor+ very low series resistance inductor
● Filter = LC output filter (1µF+30µH for 4Ω and 0.5µF+60µH for 8Ω)
All measurements are done with CS1=1µF and CS2=100nF (see Figure 2), except for the
PSRR where CS1 is removed (see Figure 3).
