[1] RsL is the series resistance of low-pass LC ï¬lter inductor in the application.

[2] Output power is measured indirectly; based on RDSon measurement; see Section 13.3.

[3] Total harmonic distortion is measured from 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] 22 Hz to 20 kHz, using an AES17 20 kHz brickwall ï¬lter; low noise due to BD modulation.

[6] 22 Hz to 20 kHz, using an AES17 20 kHz brickwall ï¬lter; independent of Rs.

[7] Vi = Vi(max) = 1 V (RMS); fi = 1 kHz.
