[1] RsL is the series resistance of inductor of low-pass LC filter in the application.
[2] Output power is measured indirectly; based on RDSon measurement. See also Section 13.3.
[3] Total harmonic distortion is measured in a bandwidth of 22 Hz to 20 kHz, using AES17 20 kHz brickwall filter. Maximum limit is
guaranteed but may not be 100 % tested.
[4] Vripple = Vripple(max) = 2 V (p-p); Rs = 0 Ω.
[5] B = 22 Hz to 20 kHz, using AES17 20 kHz brickwall filter.
[6] B = 22 Hz to 22 kHz, using AES17 20 kHz brickwall filter; independent of Rs.
[7] Po = 1 W; Rs = 0 Ω; fi = 1 kHz.
[8] Vi = Vi(max) = 1 V (RMS); fi = 1 kHz.
