[1] Rs is the series resistance of inductor of low-pass LC filter in the application.
[2] Output power is measured indirectly; based on RDSon measurement.
[3] THD+N is measured in a bandwidth of 20 Hz to 20 kHz, AES17 brick wall.
[4] Maximum Vripple = 2 V (p-p); Rs = 0 Ω.
[5] B = 20 Hz to 20 kHz, AES17 brick wall.
