Electrical characteristic curves
The graphs shown in this section use the following abbreviations:
●
RL+ 15H or 30H = pure resistor + very low series resistance inductor
●
Filter = LC output filter (1F+30H for 4
Ω and 0.5F+60H for 8Ω)

VRMS
1.
Dynamic measurements - 20*log(rms(Vout)/rms(Vripple)). Vripple is the superimposed sinus signal to VCC @ f = 217Hz.
