Audio amplifier section
The graphs included 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+6 0µH for 8 Ω).
●
All measurements done with Cs1 = 1 µF and Cs2 = 100 nF except for PSRR where Cs1
is removed.
