[1] RsL is the series resistance of inductor of low-pass LC ï¬lter 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 an AES17 20 kHz brickwall ï¬lter. Maximum limit is
guaranteed but may not be 100 % tested.
[4] Vripple = Vripple(max) = 2 V (p-p); Rs = 0 â¦.
[5] B = 22 Hz to 20 kHz, using an AES17 20 kHz brickwall ï¬lter.
[6] B = 22 Hz to 20 kHz, using an AES17 20 kHz brickwall ï¬lter; independent of Rs.
[7] Po = 1 W; Rs = 0 â¦; fi = 1 kHz.
[8] Vi = Vi(max) = 1 V (RMS); fi = 1 kHz.
