The THD+N measurements shown do not use an LC output filter, but use a low pass filter with a cutoff
frequency of 20 kHz so the switching frequency does not dominate the measurement. This is done to ensure
that the THD+N measured is just the audible THD+N. The THD+N measurements are shown at the highest gain
for worst case.
The LC output filter used in the efficiency curves (Figure 2 and Figure 3) is shown in Figure 1.

The ferrite filter used in the efficiency curves (Figure 2 and Figure 3) is shown in Figure 1, where L is a ferrite
bead.
