test set-up for graphs
The THD+N measurements shown do not use an LC output filter, but use a low pass filter with a cut-off 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 3) is shown in Figure 1.

The ferrite filter used in the efficiency curves (Figure 2 and 3) is shown in Figure 1, where L is a ferrite bead.
L1 = L2 = ferrite bead (part number = 2512067007Y3, manufacturer = Fair-Rite)
C1 = C2 = 1 nF
