[1] RsL is the series resistance of the low-pass LC ï¬lter inductor used in the application.
[2] Output power is measured indirectly; based on RDSon measurement; see Section 13.3.
[3] THD measured between 22 Hz and 20 kHz, using AES17 20 kHz brick wall ï¬lter; max. limit is guaranteed but may not be 100 % tested.
[4] Vripple = Vripple(max) = 2 V (p-p); measured independently between VDDPn and SGND and between VSSPn and SGND.
[5] 22 Hz to 20 kHz, using AES17 20 kHz brick wall ï¬lter.
[6] 22 Hz to 20 kHz, using AES17 20 kHz brick wall ï¬lter.
[7] Po = 1 W; fi = 1 kHz.
[8] Vi = Vi(max) = 1 V (RMS); fi = 1 kHz.
[9] Leads and bond wires included.
