traces or wiring between the output pin of the TDF8599 and the inductor to the measurement point. LC filter dimensioning is L = 10 H,
C = 1 F is used and for 2
Output power is measured indirectly based on R
Total harmonic distortion is measured at the bandwidth of 22 Hz to 20 kHz, AES brick wall. The maximum limit is guaranteed but may
not be 100 % tested.

S(L)
is the sum of the inductor series resistance from the low-pass LC filter in the application together with all resistance from PCB
